Biodiversity tends to be higher where:

(A) Solar energy is low and biogeochemical cycles are slow
(B) Solar energy is high and biogeochemical cycles are slow
(C) Solar energy is high and biogeochemical cycles are fast
(D) Solar energy is low and biogeochemical cycles are fast

Option (C)

Explanation:

Biodiversity usually refers to the different varieties of life forms that exist on earth. This includes the varieties in terms of ecosystem, and species and genetic changes.

This biodiversity is directly dependent on the region where there occurs a high amount of sunlight and precipitation. The factors such as latitude, climate, height, availability of resources are important for the growth and expansion of biodiversity. In these regions, the biogeochemical cycle also occurs rapidly, as the processes that are associated with it occur at a faster rate, thereby enhancing biodiversity.

Thus, the correct answer is option (C).
