Question and answer
The biogeochemical cycles move through biotic and abiotic regions. true or false
TRUE, In ecology-and earth-science, a biogeochemical cycle is a circuit or pathway by which a chemical-element or molecule moves through both biotic ("bio-") and abiotic ("geo-") compartments of an ecosystem. [ In effect, the element is recycled, although in some such cycles there may be places (called "sinks") where the element is accumulated or held for a long period of time. ]
