The P cycle (phosphorus cycle)

The phosphorus cycle involves the movement of phosphorus through the environment, mainly Earth’s crust, water, and living organisms. Phosphorus is released from rocks through weathering and enters soil and water. Plants absorb phosphorus from soil, which then moves through animals when they eat plants. When organisms die or produce waste, phosphorus returns to the soil or water, where it may be reused. Unlike other cycles, the phosphorus cycle doesn't involve the atmosphere significantly. It is essential for DNA, bones, and energy transfer in living beings, making it critical for life on Earth.
