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.

tropical regions exhibit the greatest biodiversity due to several key factors: (A) Tropical latitudes have remained relatively undisturbed for millions of years, allowing a longer evolutionary time for species diversification compared to temperate regions . Furthermore, (E) tropical environments are relatively constant and predictable, and (D) these constant environments promote niche specialization, leading to greater diversity . Additionally, (C) more solar energy is available in the tropics, which contributes to higher productivity and greater diversity . Statement (B) is incorrect because the sources explicitly state that tropical environments are less seasonal than temperate ones .
