They explain the sulfur cycle including where sulfur is found, what it is used for, and the specific steps of the cycle life and biogeochemical cycles the earth systems science & policy program from california state university, monterey bay provides information on the sulfur cycle and discusses the different forms sulfur takes on during its cycle. Notes: biogeochemical cycles (cycles of matter) unlike the one-way flow of energy, matter is recycled within and between ecosystems elements, chemical compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another through cycles that connect living things to the earth.
