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: -Hence, it is clear from the above-mentioned points that the cyclic flow of chemical elements between organisms and the environment in the biosphere is known as the Biogeochemical cycle.
Detailed explanation-3: -A biogeochemical cycle (or more generally a cycle of matter) is the pathway by which a chemical substance cycles (is turned over or moves through) the biotic and the abiotic compartments of Earth. The biotic compartment is the biosphere and the abiotic compartments are the atmosphere, hydrosphere and lithosphere.
Detailed explanation-4: -BIOGEOCHEMICAL CYCLES are the pathways by which elements like carbon, phosphorus, nitrogen, and sulfur, or compounds like water, flow between living organisms and the environment. Human activities can alter these cycles be producing or consuming in different quantities.
Detailed explanation-5: -The carbon cycle is nature’s way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
