The Phosphorus Cycle. The atmospheric carbondioxide is fixed by green plants during photosynthesis. Biogeochemical Cycles - . The nitrogen cycle. Many biogeochemical cycles affect our daily lives in many ways. A biogeochemical cycle can best be described as the recycling of a chemical element (such as carbon or nitrogen) between living organisms and their nonliving environment (1). However, the matter that makes up living organisms is conserved and recycled. Biogeochemical Cycles Carbon Cycle. Biogeochemical Cycle: Carbon Cycle Carbon is found in various forms on the earth such as Diamond, Graphite, Carbon dioxide in the atmosphere, Carbonate and Hydrogen Carbonate salts in various minerals and in endoskeletons and exoskeletons of various Animals and in molecules essential for life such as Proteins, Salt, Nucleic Acids, Vitamins PLAY. Phosphorus is an essential nutrient for living processes; it is a major BIOGEOCHEMICAL CYCLES: The changes that particular elements undergo as they pass back and forth through the various earth systems and particularly between living and nonliving matter. 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. The most common of these are the carbon and nitrogen cycles. The carbon cycle refers to the circular flow of carbon in the physical environment and the living environment. Carbon is exchanged and cycled between atmosphere, ocean layers, land and lithosphere through processes such as photosynthesis, decomposition, respiration, and mineralization. A prime example of one of these cycles is the water cycle. Carbon is stored for long periods in what are known as carbon reservoirs , which include the atmosphere, bodies of liquid water (mostly oceans), ocean Carbon fixation and respiration - plants/photosynthetic take energy from sun to convert CO2 into organic carbon (basis of food chain); _____% energy that reaches earth is utilized by photosynthesizers; 10% efficeincy in processing food, microbes responsible for about _____ photosynthesis; _____ more important than thought as occur in wide variety of areas; if only the flow of chemical elements between living organisms and the environment. The carbon is then stored in different form of carbohydrates in plant body. The nitrogen cycle. The carbon cycle overlaps the rock cycle. Sponsored by NASA, the archive includes field data, remote-sensing data, imagery, and the results of ecosystems modeling. The abundance of greenhouse gases in the atmosphere is controlled by biogeochemical cycles that continually move these components between their ocean, land, life, and atmosphere reservoirs.
