Of all terrestrial biomes, which, when mature, has the greatest species diversity?
Explanation
Answer: B - Mature tropical rainforests have the greatest species diversity of all terrestrial biomes.
Key Takeaway: Of all of the nine major terrestrial biomes (tundra, taiga, temperate deciduous forest, temperate rain forest, tropical rain forest, savanna, temperate grasslands, shrub lands, and desert), mature tropical rainforests have the greatest species diversity (also known as biodiversity). This biodiversity then tends to decrease as you move away from the equator, toward the poles.
