    The phosphorus cycle describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Phosphorus moves slowly through soils and oceans but quickly through plants and animals. It cycles from rocks to soils to organisms and back into soils or sediments over long time periods. Phosphorus enters ecosystems from weathering phosphate rocks and is recycled through decomposition.

    Phosphorus cycle

    The phosphorus cycle is the biogeochemical


    cycle that describes the movement of
    phosphorus through the lithosphere,
    hydrosphere, and biosphere.
    The cycle

     The phosphorus cycle is long and slow, but it is an


    important part of the environment. It helps plants
    grow, and is used by farmers to fertilize them.
    When animals eat the plants, they absorb
    phosphates.
     Phosphates move quickly through plants and
    animals; however, the processes that move them
    through the soil or ocean are very slow, making
    the phosphorus cycle overall one of the slowest
    biogeochemical cycles.
     When the animals die, their body decays and
    the phosphorus is absorbed into the soil,
    where it re-enters plants. What isn’t absorbed
    by plant sends up in rock, and may stay there
    for millions of years, slowly being released as
    the rocks weather.
    Atmosphere

     The Phosphorus cycle has no involvement in


    the atmosphere, because it does not naturally
    form in gaseous forms.
    Hydrosphere

     Phosphorous usually enters the hydrosphere


    by the phosphate salt rocks found on the
    ocean floor. As the water erodes them away,
    the phosphorous escapes.
     Marine organisms take some of the
    phosphorus particles in order to live and
    grow.
    Lithosphere

     Phosphorous is presented in the form of rocks


    and soil. Phosphates go down to the bottom
    of the ocean and forms rocks over million of
    years.
     Phosphates enters the soil when plant and
    animal matter decompose, the cycle repeats.
    Biosphere

     Phosphate is in plants, which the herbivores


    eat, which the herbivores are eaten by the
    carnivores. Than phosphorus is released back
    into the soil by the herbivores and carnivores
    waste.
    Human Inputs to the Phosphorus
    Cycle

     Human influences on the phosphate cycle


    come mainly from the introduction and use of
    commercial synthetic fertilizers.
