Carbon and/or carbon dioxide are also released when dead plants and animals are decomposed by bacteria and fungi. The cyclic flow of nutrients between non living environment and living organisms is known as biogeochemical cycles. Importance of Biogeochemical Cycle. The heat, pressure and chemical changes convert them into fossil fuels like coal, petroleum and gas. Ans- Biogeochemical cycles are which include both biological, geological and chemical or physiochemical pathways. The global water cycle is in steady state as total precipitation is balanced by total evaporation. The water cycle is the cyclic process of water between various components of the biosphere which includes evaporation of water from the sea, falling of water on land and then flowing back into the sea by rivers. Carbon is an element found in nature. in the atmosphere. Biogeochemical Cycle Definition. Biogeochemical, as a term, refers to three aspects in each cycle. 3. The Nitrogen Cycle Nitrogen makes up 78 percent of Earth’s atmosphere. It is the biogeochemical cycle by which nitrogen is converted into several forms and … It's found in the shiniest diamonds and in the Fossil fuels, we use to run our cars. It affects the marine and terrestrial food chains. Some of the solar radiations are reflected away by the atmosphere and Earth, while some of the Infrared rays is absorbed and re-emitted in all directions by the greenhouse gas molecules. The cycling of chemicals between the biological and the geological world is called biogeochemical cycle. A biogeochemical cycle or an inorganic-organic cycle is a circulating or repeatable pathway by which either a chemical element or a molecule moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere and hydrosphere) components of an ecosystem. It is the process of transfer and circulation of the essential chemical nutrients such as Oxygen, Hydrogen, Carbon and Nitrogen in a biosphere. It is present in all amino acid, nucleic acid and vitamins. Ammonification: Once, the plants or the animals die, part of the plant proteins is broken down into nitrogenous animal proteins. Greenhouse gases include water vapour, methane, ozone, nitrous oxide, and carbon dioxide. Nitrogenous wastes are then excreted out which are acted upon by decomposing bacteria for decomposition. Fossil fuels such as coal, petroleum and natural gas on burning also release CO2 and carbon monoxide into the atmosphere. Biology. What is the Biogeochemical Cycle Biogenic elements (macro-, micro- & other elements) flow from the environment into and out of the plant in a cyclic manner. EXAM Tips: Chlorofluorocarbons (CFCs), widely used as refrigerants, are mainly responsible for the depletion of ozone layer. These nutrient cycles in nature are called biogeochemical cycles.
