Bio-geochemical cycles
Microorganisms, in the course of their growth and metabolism, interact with each other in the cyc.1ing of nutrients, including carbon, sulphur, nitrogen, phosphorus, iron and other trace elements. This nutrient cycling called bio-geochemical cycling, when applied to the environment, involves both biological and chemical processes.

Nutrients are transformed and cycled, often by oxidation-reduction reactions that can change the chemical and physical characteristics of the nutrients. All of the bio-geochemical cycles are linked and the metabolism related transformations of these nutrients have global-level impacts.
