A biogeochemical cycle is the pathway through which a chemical substance moves through both the biotic (living) and abiotic (non-living) components of an ecosystem. These cycles involve biological, geological, and chemical processes that result in the transformation and distribution of essential elements and compounds within the environment. Key examples of biogeochemical cycles include the carbon cycle, nitrogen cycle, phosphorus cycle, and water cycle. Each of these cycles plays a crucial role in maintaining ecosystem balance and supporting life by facilitating the recycling of nutrients and energy within the biosphere.
