The Sulfur Cycle
Sulfur comes into contact with air and is. converted into sulfate (SO4) ions. The sulfate is taken up by plants and. microorganisms, converted into organic forms. Animals consume organic molecules containing. sulfur, sulfur moves through the food chain. The death and decomposition of organisms release.

13.2: The global sulfur cycle
Sulfur is an essential element for the macromolecules of living things. As a part of the amino acid cysteine, it is involved in the formation of disulfide bonds within proteins, which help to determine their 3-D folding patterns and, hence, their functions. As shown in Figure 13.2.1 13.2. 1, sulfur cycles between the oceans, land, and atmosphere.

Biogeochemical Cycles: the Sulfur Cycle
The Biogeochemical Sulfur Cycle Sulfur is essential to biological systems and is a component of certain amino acids, such as cysteine, which plays an important role in the structure of proteins. Sulfur is distributed to terrestrial (i.e., land) ecosystems by the precipitation of weak sulfuric acid, direct fallout from the atmosphere, weathering ...
Sulfur Cycle | SpringerLink
The modern natural global sulfur cycle is dominated by processes involving transfer of sulfur in and out of the oceans (Sievert et al. 2007).A significant amount of sulfur is lofted into the air in the form of small sulfate-containing salt crystals; see Fig. 1.Most of the particles settle rapidly back into the ocean, but some are transported over …
Microbially Driven Sulfur Cycling in the …
Sulfur (S) is an essential biological element, and S cycling is mainly driven by metabolically versatile microorganisms. The river–wetland–ocean (RWO) continuum here is defined as the dynamically connected region with estuary, wetland, and near-marine ecosystems, and it is considered a hotspot of biogeochemical cycling, especially a major biotope for S …

16.4F: The Sulfur Cycle
The sulfur cycle describes the movement of sulfur through the geosphere and biosphere. Sulfur is released from rocks through weathering, and then assimilated by microbes and plants. It is then passed up the food chain and assimilated by plants and animals, and released when they decompose. Many bacteria can reduce sulfur in small …

Kansas State University. In the sulfur cycle, microorganisms cycle sulfur among compounds with oxidation states ranging from −2 − 2 and +6 + 6. Reflecting this broad range of oxidation states, sulfur compounds participate in a wide variety of oxidation reduction reactions, which results in a complex cycle (Fig. 5.7 5.7 ).
