Question
Describe the model of phosphorus cycle in the terrestrial ecosystem.

Answer
Phosphorus a major constituent of biological membrane/ nucleic acids/ cellular energy transfer system, Many animals need it for making shells/ bones and teeth, the natural reservoirs of phosphorous is rock, which contains phosphorous in the form of phosphate reserves, on weathering minute amount of phosphate dissolve in soil solution, and absorbed by roots, Herbivores, obtain these elements from plants waste products and dead organism, decomposed by phosphate-solubilising bacteria, releasing phosphorus.
