Term Biogeochemical cycle
Definition

The natural process by which chemical elements are recycled repeatedly between organisms and their environment. Bio refers to organisms; geo to rocks, soil, air, and water on the planet; and chemical to the reactions that take place allowing the transfer from one place to another.

There are two types of biogeochemical cycles: gaseous and sedimentary. The main deposits of gases are in the atmosphere, and are deposits of carbon and nitrogen, among other gases. The main deposits for sedimentary cycles are in the earth’s crust, and are deposits of phosphorus, calcium, potassium, or sulfur.
