Biogeochemical cycles can be divided into two broad types:

Local cycles, which involve elements with no atmospheric mechanism for long-distance transfer. Ex- The phosphorus cycle

Global cycles, which involve an interchange between the atmosphere and the ecosystem. Ex- The carbon, Nitrogen, Sulfur, and Water
