Where Does the Bulk of Biogeochemical Cycling Occur

Question

Where does the bulk of biogeochemical cycling occur?
A) in the air
B) in soil
C) in water
D) in the benthic zone
E) in both air and water

Accepted Answer

The bulk of biogeochemical cycling occurs in soil, where nutrients are taken up by plants, decomposed by microbes, and then reabsorbed by other organisms in a continuous cycle. While biogeochemical cycling does occur in air, water, and the benthic zone, the majority of cycling happens in soil.
