Question

Which two processes make phosphates available in the soil for use by land plants?

Answer 1

Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil. The plants may then be consumed by animals.
