One thing that ALL biogeochemical cycles have in common is

they involve the movement of specific chemicals between living and non-living things.

they involve the changing of carbon into carbon dioxide.

they are pathways for elements that get passed between only non-living things.

they involve the movement of specific chemicals between living and non-living things.

The biogeochemical cycles move through mainly the biotic and abiotic components of the earth, more elaborately the spheres - biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology - involves the biological, geological and chemical components that make out to complete an exact and purposed cycle.
