The process by which chemical elements of the matter and energy moves between the biotic and the abiotic component of the biosphere along with dissipation of energy as heat to the atmosphere is generally termed as biogeochemical cycle.
Explanation:
The energy flows across food chain with entry in the form of sunlight and moves along the food chain until it is dissipated as heat. The matter which forms the basic components of the biotic part namely water, carbon, nitrogen, oxygen, phosphorus and sulfur are recycled gradually on moving through the food chain. The biogeochemical cycle may be water cycle which is most important for survival of life. Carbon cycle includes the macro molecules of organic nature and even the fossil fuels. Nitrogen cycle includes DNA, RNA and protein. Likewise all the biogeochemical cycle are invariably connected to the food chain and forms integral part of it.
