Correct answer is D. One plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that tropical regions have very high rates of immigration and very low rates of extinction.
Why do the tropics have such a diverse array of species?
Tropical regions tend to have higher concentrations of different plant, animal, and fungal species, which diminish as you move farther from the equator. This phenomenon is known as the latitudinal diversity gradient.
The most important conclusion to draw from this is that species diversity increases far more fast with rising temperatures than population size and NPP do. This shows that productivity cannot account for the LDG in its whole. Instead, it suggests that relatively direct kinetic mechanisms account for the majority of the LDG's causes. The greater temperatures in the tropics result in enhanced metabolic rates, ecological dynamics, and coevolutionary processes that create and sustain more biodiversity.
