The correct answer is: C.Weathering

The physical and chemical breakdown of rocks that releases phosphate ions is known as weathering. Weathering refers to the natural processes that break down rocks into smaller particles or dissolved ions. In the case of phosphate, weathering of phosphate-containing rocks, such as apatite, releases phosphate ions into the soil and water, making them available for plant uptake.

Breakdown of terms:

1.Weathering: This is the correct term. It involves both physical (mechanical) and chemical processes that break down rocks, releasing minerals and ions, including phosphates, into the environment.

2.Decomposition: Refers to the breakdown of organic matter by microorgan...
