Ecologist have proposed following explanation to lead maximize biodiversity at tropic.

A. Higher productivity in the tropics allows for more species present

 B. Old communities have greater species than younger community

 C. Natural enemies such as predators and parasite limit competition in the tropics, which allows more species to coexist

D. Very less intensity of disturbances in the tropics promote high succession diversity
