Answer and explanation;
-Biogeochemical cycles function to conserve and recycle the matter that is part of living organisms. There are several biogeochemical cycles on Earth including water, carbon, nitrogen, oxygen, phosphorous, sulfur and rock.
-The most important biogeochemical cycles affecting ecosystem health are the water, carbon, nitrogen, and phosphorus cycles. The biogeochemical cycles always have a state of equilibrium. The state of equilibrium occurs when there is a balance in the cycling of the elements between compartments.
