Carbon, Nitrogen, Phosphorus Cycle
The Carbon Cycle- The series of processes by which carbon compounds are interconverted in the environment.
The Nitrogen Cycle- The series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms.
-Nitrogen Fixation is a process by which nitrogen in the atmosphere is converted into ammonia.
The Phosphorus Cycle- The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
