Tropical regions show greatest level of species richness because A. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification. B. Tropical environments are more seasonal. C. More solar energy is available in tropics. D. Constant environments promote niche specialization. E. Tropical environments are constant and predictable. Choose the correct answer from the options given below.

Correct answer: A

The correct answer is:

Option A: A, C, D and E only

A. Tropical latitudes have remained relatively undisturbed for millions of years, hence more time was available for species diversification. This is a major factor contributing to species richness in the tropics. The absence of major geological events like glaciation has allowed for continuous evolution and diversification.
C. More solar energy is available in tropics. This leads to higher productivity, supporting a greater number of species.
D. Constant environments promote niche specialization. Stable conditions allow species to specialize and adapt to specific niches, leading to greater diversity.
E. Tropical environments are constant and predictable. This allows species to evolve specific adaptations to their environment, leading to further specialization and diversification.

Statement B is incorrect: Tropical environments are less seasonal, not more seasonal.
