| Tropical rain forest, in which neither water nor low temperature is a limiting factor, is by far the richest biome in terms of number of plant and animal species. The trees are evergreen and characterized by medium-sized leathery leaves. A poorly developed layer of herbs grows on the forest floor, but there are many vines and epiphytes in the illuminated zone far above the forest floor. Tropical soils are often acidic and very poor in nutrients; such soils lose their fertility rapidly when the forest is cleared. This biome now is estimated to be about half the forested area of the earth, but sadly it is in the process of being systematically destroyed by human activities. |
