Explain the Biogeochemical Cycles of Biosphere?

The bio geochemical cycles are of two types mainly. They can be gaseous or sedimentary. In the gaseous cycles the bio genetic materials involved are the gases. They can be nitrogen, oxygen, carbon dioxide and water vapor. The water forms the reservoir pool. These are quick cycles and take very less time to complete. In the sedimentary cycles the bio genetic materials involved are the non gaseous. These are not quick cycles and take a long time to complete. The lithosphere forms the reservoir pool. It includes the phosphorus and sulphur. It takes place through the food chain. This process can take million years to complete in some cases. There are some important bio geochemical cycles which are discussed below.
