geochemical cycles

Geochemical cycles refer to the natural processes that circulate essential elements and compounds in the environment. These cycles, such as the carbon, nitrogen, and water cycles, involve the movement of these substances between the atmosphere, land, oceans, and living organisms. For example, carbon dioxide is absorbed by plants during photosynthesis, released by animals during respiration, and stored in oceans and soils. These interconnected systems help sustain life on Earth and regulate climate. Understanding geochemical cycles is crucial for addressing environmental challenges and promoting sustainability.
