The Phosphorus Cycle By: Jermaine Loutin (Jose Marti Six Form Envi.)

The Phosphorus Cycle The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere. By: Jermaine Loutin (Jose Marti Six Form Envi.)

The Phosphorus Cycle 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.)

Importance of the Phosphorus cycle Phosphorus is an essential nutrient for plants and animals It is a part of DNA-molecules and RNA-molecules, molecules that store energy (ATP and ADP) By: Jermaine Loutin (Jose Marti Six Form Envi.)

Importance of the Phosphorus cycle Phosphorus is also a building block of certain parts of the human and animal body, such as the bones and teeth. By: Jermaine Loutin (Jose Marti Six Form Envi.)

A GLOBAL VIEW OF THE PHOSPHORUS CYCLE The phosphorus cycle occurs when phosphorus moves from land to sediments in the seas and then back to land again. By: Jermaine Loutin (Jose Marti Six Form Envi.)

A GLOBAL VIEW OF THE PHOSPHORUS CYCLE 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.)

By: Jermaine Loutin (Jose Marti Six Form Envi.)

Difference in the Phosphorus cycle phosphorus is unable to achieve the gaseous state in the atmosphere. Phosphorus is mainly found in water, soil and sediments. By: Jermaine Loutin (Jose Marti Six Form Envi.)

Difference in the Phosphorus cycle phosphorus is found as fine dust particles. By: Jermaine Loutin (Jose Marti Six Form Envi.)

In comparison to nitrogen and carbon, the rate at which phosphate salts are released is extremely slow. By: Jermaine Loutin (Jose Marti Six Form Envi.)

Phosphorus can remain in rocks or sediments for millions of years By: Jermaine Loutin (Jose Marti Six Form Envi.)

QUESTIONS What is the phosphorus cycle? How is the phosphorus cycle different from the other biogeochemical cycles? Name two importance of phosphorus to plants and/or animals. Name the main way in which phosphorus is released ‘naturally’ in the environment. Name two ways humans help to release phosphorus in the environment By: Jermaine Loutin (Jose Marti Six Form Envi.)
