Sulfur is found in nature in a combined state with other elements like nitrogen, iron, and phosphorus, so the sulfur cycle also affects the availability of other elements. Sulfur bacteria are chemoautotrophic organisms that can convert the chemical energy into other forms through the food chain, which increases the biomass on the planet.

Phosphorus Cycle
Phosphorus Cycle Definition. The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere. Phosphorus is essential for plant and animal growth, as well as the health of microbes inhabiting the soil, but is gradually depleted from the soil over time. The main biological …
Biosphere
Biosphere - Cycling, Phosphorus, Nutrients: Most other major nutrients such as phosphorus, potassium, magnesium, iron, and calcium enter terrestrial communities through the weathering of bedrock. These nutrients lack a volatile gaseous state. Consequently, they cycle through the biosphere differently from carbon, nitrogen, and …

Nutrient Cycles: Phosphorus, Nitrogen, and Sulfur
It is clear, then, that nutrients are inextricably linked to almost all other ecological processes. In this chapter we look at the transformations, exchanges, and general dynamics of three nutrients: phosphorus, nitrogen, and sulfur. The dynamics of these three elements illustrate how nutrients interact with sediments and water, and the great ...
Phosphorus and Sulphur Cycling in Terrestrial Ecosystems
Phosphorus (P) and sulphur (S) are essential elements for all living cells. Among the biomolecules that contain P are nucleic acids (DNA and RNA), phospholipids, sugar phosphates (e.g. glucose-6-phosphate) and molecules with an energy-rich pyrophosphate bond (e.g. ATP), whereas S is contained in two amino acids (cysteine and methionine) …
Chapter 5 ~ Flows and Cycles of Nutrients
Describe the cycles of carbon, nitrogen, phosphorus, and sulfur. Nutrients We can distinguish two basic types of nutrients: (1) inorganic chemicals that autotrophic organisms require for photosynthesis and metabolism, and (2) organic compounds ingested as food by heterotrophic organisms.

8.7 Biogeochemical Cycles
Like the carbon, nitrogen, and sulfur cycles, several of these additional biogeochemical cycles, such as the iron (Fe), manganese (Mn), and chromium (Cr) cycles, also involve redox chemistry, with prokaryotes playing roles in both oxidation and reduction. Several other elements undergo chemical cycles that do not involve redox chemistry.
