The biome that has the most biodiversity is the tropical rainforest. The tropical rainforest is home to over 15 million different species of animals and plants. It is estimated that the tropical rainforest is the habitat of over 50 percent of animal species that are terrestrial.
Tropical forests are found in Southeast Asia, South America and Africa. This biome type also is situated near the equator. For this reason, the climate is very hot and humid because this biome also receives an excessive amount of rainfall.
Although the rainforest floor may have few plants because of the overhead canopy of trees, there are many plants like orchids and bromeliads that grow on trees in the upper canopy. Similarly, tropical rainforests are home to diverse animals like monkeys, insects, birds, parrots, ants and reptiles.
