Web1. Elements move through these four spheres through physical processes (e.g., carbon dioxide is absorbed from the atmosphere to the ocean), biological processes (e.g., plants use carbon dioxide from the air in photosynthesis) and through human activities (e.g., burning fossil fuels moves carbon from the ground to the atmosphere). WebBiogeochemical cycles play a central role in regulating Earth's climate and the health of terrestrial and aquatic ecosystems. Carbon and nutrients naturally move through the ecosystem via the water cycle and activities of organisms (e.g., respiration, consumption, excretion, and decomposition). Human activities also impact element fluxes.
