Biogeochemical cycles on Earth serve a variety of different purposes. What do the biogeochemical cycles have in common?

Biogeochemical cycles move and recycle essential materials, such as water, carbon, and nitrogen, between living organisms and the nonliving environment. Their specific functions differ, so they do not all serve the same function, and they include both living and nonliving components. The common feature is that they are all essential for sustaining life on Earth.
