2. The Phosphorus Cycle The phosphorus cycle is thebiogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere. Unlike many other biogeochemical cycles,the atmosphere does not play a significant role in the movements of phosphorus. By: Jermaine Loutin (Jose Marti Six Form Envi.) 3. Importance of the Phosphorus cycle Phosphorus is an essential nutrient forplants and animals It is a part of DNA-molecules and RNAmolecules, molecules that store energy (ATP and ADP) Phosphorus is also a building block of certain parts of the human and animal body, such as the bones and teeth.

A GLOBAL VIEW OF THE PHOSPHORUS CYCLE The phosphorus cycle occurs whenphosphorus moves from land to sediments in the seas and then back to land again. The main storage for phosphorus is in the earths crust. On land phosphorus is usually found in the form of phosphates By: Jermaine Loutin (Jose Marti Six Form Envi.) 7. By: Jermaine Loutin (Jose Marti Six Form Envi.) 8. Difference in the Phosphorus cycle The phosphorus cycle differs from the nitrogen andcarbon cycles because phosphorus is unable to achieve the gaseous state in the atmosphere. Phosphorus is mainly found in water, soil and sediments. In the atmosphere, phosphorus is found as fine dust particles.By: Jermaine Loutin (Jose Marti Six Form Envi.) 9. Incomparison to nitrogen and carbon, the rate at which phosphate salts are released is extremely slow. Phosphorus can remain in rocks or sediments for millions of years By: Jermaine Loutin (Jose Marti Six Form Envi.) 10.
