Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. Once in the plant or animal, the phosphate is incorporated into organic molecules such as DNA. i hope this helped <3
Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts. Phosphate salts that are released from rocks through weathering usually dissolve in soil water and will be absorbed by plants. ... When animals and plants die, phosphates will return to the soils or oceans again during decay.
