Several hypotheses have been proposed to explain patterns of species diversity based on latitude.Applying one of these hypotheses, where might one expect to find the greatest species diversity, and why?
A) Tropics, because of the isolation from other biomes
B) Tropics, because of the large area and warm, stable climate
C) Temperate zones, because they extend over most of Earth
D) Temperate zones, because their distinct seasons stimulate speciation
E) Polar zones, because high ocean productivity overcomes high extinctions

Question

Quizplus · Accepted Answer

The hypothesis of greater species diversity in the tropics is based on the idea that the warm, stable climate and large area provides more opportunities for speciation and the coexistence of diverse species. Therefore, the best choice is B - Tropics, because of the large area and warm, stable climate.
