The biotic and abiotic components of the biosphere constantly interact through biogeochemical cycles. 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.

Carbon is exchanged between heterotrophs and autotrophs within and between ecosystems primarily by way of atmospheric CO2, a fully oxidized version of carbon that serves as the basic building block that autotrophs use to build multicarbon, high-energy organic molecules such as gl… Biogeochemical Cycles - Biogeochemical Cycles Section 22-2 Pages 420-423 describe the flow of essential elements from the environment through living organisms and back into the environment. Define the term biogeochemical cycles. Rev. In order for these materials to be recycled, they must change states and transform! Compare and contrast how carbon, phosphorus, nitrogen, and water cycle through the environment. Global Change - The Science of Sustainability (Fall term) Global Change - The Sustainability Challenge (Winter term) The University of Michigan's Global Change Courses, part of the Program in the Environment, offer a modern approach to undergraduate science and social science education.In interdisciplinary courses the topic of Global Change from physical and human perspectives are … Biogeochemical cycles. Donate or volunteer today! The term biogeochemical is a contraction that refers to the consideration of the biological, geological, and chemical aspects of each cycle. 2017.71:41-60. Our mission is to provide a free, world-class education to anyone, anywhere. Pete's PowerPoint Station is your destination for free PowerPoint presentations for kids and teachers about Biogeochemical Cycles, and so much more. There is one worksheet for each cycle, and the final worksheet is titled "Name That Cycle" where students need to identify the correct cycle it is referring to. For every cycle the lesson includes a diagram of the cycle, explains why the nutrient is important, explains how it moves, and human impact. Death and decay also contribute to the biogeochemical cycles. We emphasize differences in biogeochemical cycles between estuarine and marine ecosystems and lakes.
