<P> The sulfur cycle is the collection of processes by which sulfur moves to and from rock, waterways and living systems . Such biogeochemical cycles are important in geology because they affect many minerals . Biochemical cycles are also important for life because sulfur is an essential element, being a constituent of many proteins and cofactors . </P> <P> Steps of the sulfur cycle are: </P> <Ul> <Li> Mineralization of organic sulfur into inorganic forms, such as hydrogen sulfide (H S), elemental sulfur, as well as sulfide minerals . </Li> <Li> Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO). </Li> <Li> Reduction of sulfate to sulfide . </Li> <Li> Incorporation of sulfide into organic compounds (including metal - containing derivatives). </Li> </Ul> <Li> Mineralization of organic sulfur into inorganic forms, such as hydrogen sulfide (H S), elemental sulfur, as well as sulfide minerals . </Li>
