Tropical Rainforest

By: Wesley Marlow


A tropical rainforest is a biome that is very humid. It is very hot, and gets a lot of rain. Almost 150 cm per year of rain. These forests produce 40% of the Earths oxygen and only cover about 6% of Earth. Rainforest's can be found in Central America as well as Africa and Indo-Malaysia.

Abiotic Factors

Abiotic factors include water, the climate, soil nutrients, and sunlight.

Biotic Factors

Biotic factors in a Tropical Rainforest are simply different. Not only are there different types of animals not seen anywhere else, but the colors and features of these animals are like no other. Characteristics involve bright colors, sharp patterns and a very fruitful diet. Nutrients, though, is to be desired. These nutrients are washed away from the shallow soil with rain after rain. These nutrients can be found in plants, but as they decompose little organisms such as insects and micro organisms such as bacteria and fungi get decomposing plant matter and turn them into nutrients.

Liana is an example of plant adaptation. These plants climb up tree's to get sunlight and then send roots down into the ground. An animal example is snakes for the adaptations of animals. These animals roam the ground instead of upper layers.

Community Interactions

Primary producers consists of trees, shrubs and other plant life. Primary consumers are bugs and birds such as Toucans. And secondary consumers are animals such as cheetah's and chimpanzee's.

Human Interactions

Deforestation is a big impact on the rainforest. Rainforest's used to be 14% of the earth, but now because of deforestation it's only 6%.


The Tropical rainforests give earth more the 40% of its oxygen. Without these rainforests there would be a limited and scarce amount of oxygen. Rainforests also help stabalize Earth's climate. By absorbing carbon dioxide, rainforest help reduce effects on the Earth's climate. These forests help maintain the water cycle by constantly recycling water throughout the Earth. As rainforests decrease in size, drought happens in different areas of the world, by affecting the water cycle.
