Three key biogeochemical cycles often discussed are the carbon cycle, nitrogen cycle, and phosphorus cycle. The carbon cycle involves the movement of carbon among the atmosphere, oceans, soil, and living organisms, playing a crucial role in regulating Earth’s climate. The nitrogen cycle describes the transformation and movement of nitrogen through the atmosphere, soil, and living organisms, essential for amino acids and nucleic acids. Lastly, the phosphorus cycle focuses on the movement of phosphorus through soil, water, and living organisms, vital for energy transfer and cellular function, but it does not have a significant gaseous phase like the other two cycles.
