The sulfur biogeochemical cycle is a sedimentary cycle with essentially no gaseous cycle.

Question

Quizplus · Accepted Answer

The sulfur biogeochemical cycle has both a sedimentary and a gaseous cycle. The sedimentary cycle involves the weathering of rocks containing sulfur minerals, the release of sulfates into soils and water, and the uptake of sulfates by plants and microorganisms. The gaseous cycle involves the conversion of organic sulfur compounds to hydrogen sulfide gas by bacteria, which can be oxidized back to sulfate or reduced to elemental sulfur, completing the cycle.
