Final answer:
Phosphorus moves from the geosphere to the biosphere through the phosphorus cycle, which involves weathering of rocks, absorption by plants, and consumption by animals and decomposition.
Step-by-step explanation:
Phosphorus moves from the geosphere to the biosphere through a cycle known as the phosphorus cycle. The process begins with the weathering of rocks, where phosphate minerals are released into the soil. These phosphates are then taken up by plants through their roots, and phosphorus moves into the biosphere through the consumption of plants by animals and the decomposition of organic matter.
