 New Biogeochemical Cycle: The
Phosphorus Cycle.

 Phosphorus cycle: The biogeochemical cycle
that describes the movement of phosphorus
through the lithosphere, hydrosphere, and
ecosphere.

• Ecosphere: The surface of the earth and
all the ecosystems.

• Lithosphere: Below the surface, in the
crust and mantle.

• Hydrosphere: All waters not in atmosphere
and lithosphere.

• Atmosphere: The area of gases that
surround the planet.

• Atmosphere: Not a part of the Phosphorus
Cycle
