Phosphorus Cycle
- Phosphorus is a major constituent of biological membranes, nucleic acids and cellular energy transfer systems.
- Many animals also need large quantities of this element to make shells, bones and teeth.
- The natural reservoir of phosphorus is rock, which contains phosphorus in the form of phosphates.
- When rocks are weathered, minute amounts of these phosphates dissolve in soil solution and are absorbed by the roots of the plants.
- Herbivores and other animals obtain this element from plants.
- The waste products and the dead organisms are decomposed by phosphate-solubilising bacteria releasing phosphorus.
- The differences between carbon cycle and phosphorus cycle are:
- Unlike the carbon cycle, there is no respiratory release of phosphorus into the atmosphere.
- The atmospheric inputs of phosphorus through rainfall are much smaller than carbon inputs.
- The gaseous exchanges of phosphorus between organism and environment are negligible.
