Overview
A Tropical rainforest is a tropic ecosystem and are usually found along the equator.You normally find them in Asia, Australia, Africa, South America, Central America, Southern Mexico and on many of the Pacific Islands. Tropical rainforests are considered a type of tropical wet forest. Rainforests are home to half of all the living animal and plant species on the planet.Tropical rain forests are called the "world's largest pharmacy" because over one-quarter of modern medicines originate from its plants.The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level.This makes it possible for people and other animals to walk through the forest. If the leaf canopy is destroyed or thinned for any reason, the ground beneath is soon colonized by a dense tangled growth of vines, shrubs and small trees called a jungle
Physical Factors
The mininum annual rainfall is between 1,750 millimetres and 2,000 milimetres. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year
Over two-thirds of the world's rainforests, and three-fourths of the Amazonian rainforest can be considered "wet-deserts" in that they grow on red and yellow clay-like laterite soils which are acidic and low in nutrients. Many tropical forest soils are very old and impoverished, especially in regions—like the Amazon basin—where there has been no recent volcanic activity to bring up new nutrients. Amazonian soils are so weathered that they are largely devoid of minerals like phosphorus, potassium, calcium, and magnesium, which come from "rock" sources, but are rich with aluminum oxide and iron oxide, which give tropical soils their distinctive reddish or yellowish coloration and are toxic in high amounts. Under such conditions, one wonders how these poor soils can appear to support such vigorous growth.
