Phosphorus Cycle

Learn about the Phosphorus cycle. Phosphorus is an essential nutrient for living organisms. It’s a building block of nucleic acids, like DNA, and phospholipids that form our cell membranes. It is also essential for plant growth.
In the natural world phosphorous is never encountered in its pure form, but only as phosphates, which consists of a phosphorus atom bonded to four oxygen atoms
Phosphate compounds are found in sedimentary rocks, and as the rocks weather—wear down over long time periods—the phosphorus they contain slowly leaches into surface water and soils. Volcanic ash and fertilizer can also be significant phosphate sources.
