Detailed explanation-1: -The ways in which an element-or compound such as water-moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.

Detailed explanation-2: -All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles. Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles.

Detailed explanation-3: -Elements pass from one organism to another and among parts of the biosphere through closed loops called biogeochemical cycles, which are powered by the flow of energy. Biogeochemical cycles of matter involve biological processes, geological processes, and chemical processes.

Detailed explanation-4: -The biogeochemical cycle involves external transfers of elements among different components of a forest system. Uptake of nutrients from the soil and return of these nutrients in leaf fall, branch shedding, root growth and death, or through tree mortality is a major component of the biogeochemical nutrient cycle.
