WebFigure 20.11 Carbon dioxide gas exists in the atmosphere and is dissolved in water. Photosynthesis converts carbon dioxide gas to organic carbon, and respiration cycles the organic carbon back into carbon dioxide gas. Long-term storage of organic carbon occurs when matter from living organisms is buried deep underground and becomes fossilized. WebJan 1, 2024 · Introduction. Biogeochemical cycle is the pathway for the circulation of the major elements in living matter (Butcher, 1993; Bertrand et al., 2015).It considers the biological, chemical, and geological aspects of the cycles and includes the movement of chemical substances through the abiotic and biotic compartment of the Earth (Bertrand et …

WebOct 4, 2024 · The geochemical cycles of elements have been operating through the entire history of the Earth, sometimes undergoing dramatic modifications by catastrophic events. During the Holocene, the natural geochemical cycles have suffered substantial alteration because of anthropic activities. WebA biogeochemical cycle (or more generally a cycle of matter [1]) 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.
