Biogeochemical cycles describe the movement of certain elements (typically bound with other elements in compounds) through Earth’s atmosphere, hydrosphere, biosphere, and lithosphere. These elements and their compounds are necessary components of all life, and because they cycle, they can be used repeatedly by new generations of organisms.

Metagenomics for the analysis of biogeochemical pathways Definition Biogeochemical cycle: the combined movement, by biology and geology, of chemical elements between Earth’s biosphere and its abiotic reservoirs. Especially important are those involving the main building blocks of life: carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
