This article focuses on the rainforest’s and its structure, both biotic and abiotic and the the cycles that gives us the ability to live on this Earth.

There are a several different types of biomes that cover the vast surface of our planet, but one in particular is very important. The Tropical Rainforest can be described as a forest of tall trees that is located in areas that receive year-round warmth. 50 to 250 inches of rain fall on these areas on average and almost all Rain Forest are located in the equator region. Tropical Rainforest are extremely important because of the oxygen that they provide to our planet, about 40% and the types of plants that have cured diseases and have helped fight ailments. Sadly, only about 6% remains of the world’s tropical forest due to deforestation (, 2012) Scientists estimate that over half of the world’s species inhabit the Rain Forest and this is why it is so import that this biome remains intact and preserved. The Amazon Rain Forest and the Rainforests in Costa Rica are examples of the biome that shelter thousands of plan t and animals species that have just as much of a right to be on Earth as we do.
The structure of the Tropical Rainforest has many layer that shelter both biotic and abiotic forms. The emergent layer is at the very top, even above the canopy and is home to birds, insects, snakes and monkeys. The next layer is the canopy where the trees leaves at the tops are tightly bound together and compete for sunlight. Here they take in carbon dioxide from the air and turn it into food through the process of photosynthesis. It’s estimated that 70-90% of rainforest life lives in the canopy. The understory layer is place that receives very little sunlight and is home to smaller…...

Un-natural actions by man have left ecosystems in a state where they cannot replenish themselves. Human caused degradation and loss to these systems return to affect human health in the end. Every ecosystem on Earth plays part to another, biodiversity, health, and sustainability are all dependant on each other. Once these factors cannot support themselves the health of an ecosystem is in peril. When society changed its habits and how it uses natural resources that in turn affect ecosystems will there be a lessened burden on ecosystems richness and sustainability. This also brings benefit to human society by having resources available farther into the future for use.

...1 Tropical Rainforest Unit 1 Individual Project Rosella Fyffe Jane Knapp 3-31-2013 2 Introduction I will be discussing the Tropical Rainforest, and writing about the abiotic components, carbon cycle, nitrogen cycle, and the ecosystem function and structure. Also discussing the disturbance and how natural can bounce back after these types of disturbance. 3 Tropical Rainforest The ecosystem of the Tropical Rainforest is a community of living organisms such as plants, animals and microbes in conjunctions with the nonliving components of their environment such as air, water and mineral soil, interacting as a system. ( Ecosystems are controlled both by external and internal factors. The external factors such as climate, this is the material which forms the soil and topography, and control the overall structure of an ecosystem and the way things work with in it. Other external factors are time, potential biota. The internal factors not only control ecosystem processes but are also controlled by them and are often subject to feedback loops. The resource inputs are generally controlled by external processes like climate and parent material. ( The ecosystem processes, is when the energy and carbon enter ecosystems through photosynthesis, are incorporated into living tissue, transferred to other organisms. The biotic and abiotic components are regarded as linked......

Rainforest Essay

...Amazon Rainforest is incredible. To see it, is to have an awe-inspiring experience. “The Amazon Rainforest has evolved over millions of years to turn into the incredible complex environment” (Amazon Rainforest) It is a beautiful landscape filled with some of the most beautiful animal and plant species on earth (see figure 1) .and is one of the world's greatest natural resources. The Amazon Rainforest produces about 20% of the earth’s oxygen because its vegetation continuously recycles carbon dioxide into oxygen. It has been described as the "Lungs of our Planet" (Amazon Rainforest). This rainforest is the world’s largest tropical rainforest and covers over a billion acres. The areas included would be Brazil, Ecuador, Columbia, Venezuela, and Peru. Figure 1 “Why is the Amazon Rainforest so important?” The Amazon is very ecologically important for many reasons. First of all, the rainforest has probably the largest collection of plant and animal species in the whole world. It is estimated that a single hectare (2.47 acres) of Amazon rainforest contains about 900 tons of living plants, including more than 750 types of trees and 1500 other plants (Rainforest Facts). The Amazon rainforest is considered the richest biological incubator in the world. Amazingly, the Andean mountain range and the Amazon jungle are the home to more than half of the world's species of flora and fauna; and are home to over 438,000 species, and many more are yet to be discovered (Rainforest......

...Forest ecosystem FOREST ECOSYSTEM A forest is more than just the trees. A single forest is a complete, functioning ecosystem that supports innumerable plant and animal species as well as earth, water, and air subsystems. The subsystems provide the essence of life of the forest and are in themselves a byproduct of forest systems, all of which are reciprocal and inter dependent. A forest ecosystem is a complex of living and non-living elements which interrelate. An ecosystem can be small (like your backyard) or large (like the planet earth). It depends on the range of individual species or group of species being discussed (e.g.: a salmon stock or a forest type), geology (e.g.: a mountain range or watershed), and other issues. Different organisms exist within the forest layers. These organisms interact with each other and their surrounds. Echo organism has a role or niche in sustaining the ecosystem. Some provide food for other organisms, other provide shelter or control populations trough predation. NEEDLE LEAF Needle leaf trees fall into two categories based on how they are attached to the twig coming off the branch of the tree. On coastal redwoods and true firs, the needles will be connected directly to the twig, growing off it like leaves off the branch of a common plant. On trees like spruce trees, the individual needles will be connected to the tree via a peg-like stalk, which is also known as a needle peg. Sometimes needles on conifers are bundled......

...HOW IS THE RAINFOREST HELPFUL TO US? Malcolm Clay ITT- Technical Institute The rainforest is helpful to us in many ways. Rainforests can be found all over the world from as far north as Alaska and Canada to Latin America, Asia and Africa. Rainforests are found on every continent across the Earth, except Antarctica. There are two major types of rainforest: temperate rainforests and tropical rainforests. The largest temperate rainforests are found on North America's Pacific Coast and stretch from Northern California up into Canada. Temperate rainforests used to exist on almost every continent in the world, but today only 50 percent — 75 million acres — of these forests remain worldwide. Rainforests act as the world's thermostat by regulating temperatures and weather patterns. One-fifth of the world's fresh water is found in the Amazon Basin. Because the rainforest cleans and recycle the water in it. Rainforests are critical in maintaining the Earth's limited supply of drinking and fresh water. The rainforest provides us with clean air because there are many plants and trees in the rainforest. The trees and plants stores the carbon dioxide in their stems and leaves, then they give off oxygen for us to breathe. The rainforest also helps absorb other chemicals such as nitrous oxide. The rainforests provide many important products for people: timber, coffee, cocoa and many medicinal products, including those used in the treatment of cancer. Seventy percent of the......

...What is an ecosystem? Well, an ecosystem includes all living things, such as animals and plants, and non-living things, such as the climate, soil and weather in a given area. Some examples of an ecosystem could be a desert, coral reef, or a rainforest. The ecosystem that has and will still to this day amaze me is the rainforest ecosystem. The rainforest can be characterized by its dense growth of trees in a very wet climate. There are tropical rainforests and temperate rainforests. The largest and in my opinion the most beautiful rainforest is the tropical. The tropical rainforest is home to more species of plants and animals than any of the other ecosystems combined. A tropical rainforest can be located near the equator. This type of rainforest is mainly in Brazil, but can also be found in Southeast Asia, the Pacific Islands, and West Africa. On the other hand, temperate rainforest can be found by the coast, the largest being by the Pacific coast of North America. The Daintree rainforest in Australia is by far the most interesting tropical rainforest. It is located north of Australia near Daintree, Queensland by the coast. This rainforest contains 30% of frog, marsupial and reptile species in Australia, and 65% of Australia's bat and butterfly species. It also contains 20 % of bird species in the country. In the rainforest there are both abiotic components and biotic components. Abiotic components are the nonliving things, such as ware, air, temperature, wind and the sun....

Tropical Forersts Problem

...Tropical forests A rainforest is a thick of tall trees which is found in tropical areas where there is a lot of rain. The largest rainforests are in the Amazon River Basin (South America), the Congo River Basin (western Africa), and throughout much of southeast Asia. Smaller rainforests are located in Central America, Madagascar, Australia and nearby islands, India, and other locations in the tropics. Due to human intervention, today more than 40% of the worlds original forests have gone, for example, In 1950, 30% of the earth was covered by tropical forest. By 1975, only 12% was left and in 2002 they now cover only about 6% of the earth land. Forests exploited for wood and new agricultural terraces. If deforestation process will not be stopped or controlled, it will lead to appearance of big problems for those who is living and working in forests, for all humans as well. Rainforests should be protected due to their big importance for all the world, and below are just several reasons for that: - For many indigenous and other forest-dependent people, forests are their livelihood. They provide them with edible and medicinal plants, bush meat, fruits and many other goods, as well as with cultural and spiritual values. Without forests those communities will die. - The US Cancer Institute has identified more than 2000 tropical rainforests plants with potential to fight cancer. And yet, as forests come down, such plants – and the hopes they embody – are destroyed. Besides, in......

Tropical Rainforest

...Tropical Rainforest Megan L. Cleveland SCI/256 JUNE 14, 2015 Mr. Davis Tropical Rainforest An ecosystem is a unique environment where every living thing is interdependent, and one of the most complex yet most interesting ecosystems in the world will be found in the rainforest. The dark and recessed thick plant growth make it one of the most moist places on Earth. If a person studies the plants and animals that compromise the rainforest ecosystem; a person can gain a basic understanding of why scientists and ecologists alike are concerned about the disappearing tropical jungles. Rain forests have the most complex and species rich ecosystems on Earth. A rain forest biome is very complex; including a myriad of different species or plants and animals that have all adapted to lots of rain. They have different levels of plants; the highest level are full of tall trees and they are for the closed canopy. Vines are the next level, such as orchids and epiphytes that grow high within the trees to reach more sun light. The lowest level belongs to the short trees and small plants, like ferns. At the base of it all is the forest floor; dark but full of life. Rainforests support more than eight thousand kinds of plant within their dense vegetation. Australian rainforests produce flowers that are not found in any other place in this world. At ground level of a rainforest, it is so dark it may seem like dusk at lunchtime because of the layers of leaves blocking the light....

Deforestation of Tropical Forests

...Deforestation of Tropical Rainforests Gabriel Corbeil ENV/GEO 120 March 20, 2015 Introduction: Tropical rainforests represent an important percentage of the globes biodiversity. This ecosystem is estimated to house 50% of all plant, insect and animal life. Covering less than 7% of Earth’s surface, it nonetheless is attributed with producing 20% of our oxygen supply. This unique biome arcs like a green arrow along the equatorial line. Its primary locations are South America, Central Africa and South-East Asia. Each region is facing varying degrees of serious deforestation. The result being widespread loss of humid tropical forest “Between 1990 and 1997, 5.8 ± 1.4 million hectares of humid tropical forest were lost each year, with a further 2.3 ± 0.7 million hectares of forest visibly degraded.” (Achard et al. 2002) The heart of the problem lies beneath a tangled mess of socio-economic growth resulting in massive deforestation chiefly for the land. Commercial farmers using the land for cattle, soybeans, palm oil and monoculture tree farms take advantage of loose government regulations. The most common tactic for land for forest removal is “slash and burn” where existing vegetation is cut down and burned for fertilizer. This technique has major impacts on multiple cycles key to forest health. Most notably the hydrological cycle, the nitrogen cycle and the carbon cycle. If this trend continues there will be major changes in precipitation and air quality, both locally and......

Tropical Rainforest

...Tropical Rainforest Hassan Gordon American Intercontinental University The Tropical Rainforest is a forest occurring in tropical areas of heavy rainfall. In the tropical rainforest most trees in the rainforest have wide buttress roots. Deforestation is a major problem caused by humans in the tropical rainforest. The government has cleared large areas of the Amazon Rainforest and encouraged people to move there. About 80% of the rainforests nutrients comes from trees and plants. Tropical Rainforest Tropical Rainforests are located around the equator, in areas with lots of rainfall, and where temperatures consistently stay near 80 degrees’ year round. Emergents are the tallest trees that are located in a tropical rainforest, which usually can stand well over 160 feet. You also have the canopy level which is a sea of leaves blocking lower levels from the sunlight. The canopy is here nearly half the animal population is, like the monkeys, birds, snakes, and also vines that lead up from lower levels that reach the sun. Then you have the shrub layer which has the most compacted plant growth, mostly plants, and ferns that do not require much sunlight to grow, then you have the forest floor that is mostly dark, and wet which contains a layer of rotting leaves and dead animals that have decomposed creating a thin mist full of nutrients. Biochemical cycles are the pathways in which the transformation, and transport of matter takes place. There are four areas categories......

...Rain forests come in two varieties the tropical and the temperate. Areas larger and full of life in a rain forest are the tropics because an abundance of plants and species making its home there. Tropical rain forests are found in Central America, Africa, and Indo Malaysia. Tropical Rain Forest Because tropical rain forests are near the equator, temperatures are 75 to 88 degree Fahrenheit and have 80 inches of rain throughout the year. Barros Colorado Island obtains about 98 inches of rain yearly with a distinctive parch season during the months of December through April with about 12 inches of rain. Compared to any place on earth biodiversity is higher because of the different species present; About 1,185 varieties of plants, 130 kinds of endemics, 650 types of birds, and 93 species of amphibians. The four major layers that towels through the forest is the, Emergent, the canopy, understory, and the forest floor. The Emergent area has the tallest trees called, hardwood, broad-level, and evergreen that grows beyond 200 feet in height and obtain plenty of sunlight. Butterflies, eagles, bats, and monkeys live in the Emergent area. The Canopy section of the forest is the most important layer because of its flat oval shape leaves that roof over into a maze of leaves. Plenty of animals as well snakes, frogs, and toucan birds live here because of its richness in food. The understory has very little sunlight, which is why plants that grow nearly 12 feet in this area have leaves...

The Ecosystem of the Rainforest

...The Ecosystem of the Rainforest An ecosystem is a relationship among the living and non-living organisms in a designated area and the environment in which they interact with. It includes plants, trees, animals, water, and soil. The rainforest ecosystem includes a variety of species, plants, and animals. All living organisms in this ecosystem physically adapt to the rain. The climate in the rainforest is very humid due the amount of rainfall. A tropical rainforest is very hot and wet; this type of climate is hit directly by the sun because of its location near the equator. The closer you are to the equator the solar radiation there is. The average temperature reaches about 77 degrees Fahrenheit. This climates temperature remains about the same all year never dropping below 64 degrees Rain falls at about 250 cm each year. Because the sun is directly hitting the rainforest, when the sun warms the ground and sea the water evaporates into the air. Warm air vapor and cold ail vapor form eventually causing clouds to form resulting to rain. This water cycle constantly repeats itself. Rain occurs more than 90 days a year in a rainforest. The rainforest consist of mainly trees and animals, trees can reach up to 164 feet in height. Because of the climate plants such as ferns and mosses or epiphytes, receive lots of water and direct sunlight so they grow very tall. Along with the many species of plants living in the rainforest, tropical animals such as Toucans,......
