Figure: A tropical rainforest 8 oi4m pgqi - vk.3z66k5iygtqt5t ze1

Explain the high habitat diversity found in a tropical rainforest.

A. The vegetation in tropical rainforests has a complex vertical structure with many layers. This leads to many niches and, thus, high habitat diversity.

B. Tropical rainforests have high insolation and rainfall throughout the year, leading to high productivity and, thus, high habitat diversity.

C. Tropical rainforests have deep and fertile soil layers allowing for tall trees' growth. This leads to many niches and, thus, high habitat diversity.

D. Tropical rainforests are found chiefly at sea level, so problems associated with high altitude do not affect the habitat diversity.
