Solution

Rocks are natural reservoir of phosphate form of phosphorous. When rocks worn away release phosphates in soil which is then absorbed by roots. Animals obtain this element from plants and when these animals are dead they are decomposed by phosphate-solubilizing bacteria. This process releases phosphorous into soil which is again absorbed by the roots and the cycle continues.

Hence, the correct answer is option: 'A'.
