Question

why are the tropics the most diverse areas?

a. they have no predators.
b. they have the most nonnative species.
c. they have stable temperatures.
d. they have many secondary disturbances.

Explanation:

Stable temperatures in the tropics allow for consistent environmental conditions. This consistency supports a wide variety of species as it reduces the stress of extreme temperature fluctuations. Many species can thrive and co - exist, leading to high biodiversity. Option A is incorrect as predators are present in the tropics. Option B is wrong because non - native species do not contribute positively to high natural diversity. Option D is incorrect as secondary disturbances would disrupt the ecosystem and not lead to high diversity.

Answer:

C. They have stable temperatures.
