Detailed explanation-1: -What is a Biogeochemical Cycle? “Biogeochemical cycles mainly refer to the movement of nutrients and other elements between biotic and abiotic factors.” The term biogeochemical is derived from “bio” meaning biosphere, “geo” meaning the geological components and “chemical” meaning the elements that move through a cycle.

Detailed explanation-2: -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-3: -The global carbon cycle, one of the major biogeochemical cycles, can be divided into geological and biological components. The geological carbon cycle operates on a timescale of millions of years, whereas the biological carbon cycle operates on a timescale of days to thousands of years.

Detailed explanation-4: -Nutrients move through ecosystems in nutrient cycles, also known as biogeochemical cycles. Elements or molecules travel through the atmosphere, hydrosphere, lithosphere, and biosphere in dynamic equilibrium. Nutrients move from one reservoir, or pool, to another for varying amounts of time, called the residence time.

Detailed explanation-5: -It is also known as nutrient cycling. It is the movement of nutrient elements through the various components of an ecosystem.
