The Phosphorus Cycle Questions and Answers 100% Pass What is the phosphorus cycle? The phosphorus cycle is the biogeochemical process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere, involving the weathering of rocks, uptake by plants, and movement through the food chain. Where is most phosphorus found in the environment? Most phosphorus is found in rocks and sediments, where it is released through the process of weathering. How does phosphorus ente...
