2. The Phosphorus Cycle
 The phosphorus cycle is the
biogeochemical 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.

3. Importance of the Phosphorus cycle
Phosphorus is an essential nutrient for
plants 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.

6. 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. The main storage for
phosphorus is in the earths crust. On
land phosphorus is usually found in
the form of phosphates

8. Difference in the Phosphorus cycle
The phosphorus cycle differs from the nitrogen and
carbon 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.

9. In
comparison 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
