Biogeochemical cycle — Science definition
The pathway by which an element or molecule moves through living things (bio), the Earth (geo), and chemical reactions — for example, the carbon, nitrogen, and water cycles.

In use
The looping pathways that carry elements through the air, water, rock, and living tissue are called biogeochemical cycles, and three of them — carbon, nitrogen, and water — keep the biosphere running.
