Which of the following processes would convert inorganic phosphorus in a rock to an organic form of phosphorus? weathering combustion decay of dead animals plant uptake

The correct answer is option D, Plant uptake

Explanation:

Like other minerals and nutrients, plant also uptake inorganic phosphorus in the form of orthophosphate. The common source of orthophosphate is phosphoric acid. It is the root of the plants that uptakes phosphorus through the process of diffusion. Plant growth depends on the phosphorus released from the decomposition of the dead organic material as a part of biochemical cycle.

Plant uptake is the process which converts inorganic phosphorus in a rock to an organic form of phosphorus.
