What are biogeochemical cycles?

Biogeochemical cycles are integral to the functioning of ecosystems, as they describe the movement and transformation of nutrients through biological, geological, and chemical processes. This means that these cycles encompass the interactions of living organisms, the earth's materials, and chemical reactions that facilitate the recycling of essential elements like carbon, nitrogen, and phosphorus.

In these cycles, biological processes include the uptake of nutrients by plants, the consumption by animals, and the decomposition of organic matter. Geological processes involve the weathering of rocks and soil formation, while chemical processes can include reactions in the atmosphere or in bodies of water that alter the forms of these nutrients. Together, this interconnected network ensures that life-sustaining elements are available to organisms and supports ecosystem health and productivity. The holistic nature of biogeochemical cycles emphasizes their role in maintaining balance within ecosystems, underscoring their importance in ecology.
