Final answer:
The b. weathering of rocks releases phosphate into the environment, where it can be used by various food webs and contribute to ocean sediment.
Step-by-step explanation:
The process that can transform rocks into soluble phosphorus is weathering. Weathering of rocks releases phosphate ions (PO4³⁻) into the soil, water, and air, which then becomes available to terrestrial food webs. This natural process allows the phosphates to enter rivers, lakes, and oceans, where they become part of marine food webs and eventually contribute to sediment on the ocean floor.
The process that can transform rocks into soluble phosphorus is rock weathering. Weathering of rocks releases phosphate into the soil, water, and air, making it available to terrestrial food webs. This occurs when phosphates are leached from phosphate-containing rock and sent into rivers, lakes, and the ocean through natural surface runoff.
