Carbon sequestration, as a biological process, refers to the capture and long-term storage of inorganic carbon, primarily in the form of atmospheric CO₂, into organic and inorganic carbon pools mediated by living organisms. In terrestrial ecosystems, plants, fungi, and microbes fix CO₂ via photosynthesis and chemoautotrophy, transferring carbon into biomass, soils, and stable humic substances. In aquatic systems, phytoplankton, macroalgae, and microbial communities incorporate CO₂ into organic matter, some of which is exported to deeper waters and sediments through the biological pump. Biological carbon sequestration regulates carbon cycling, ecosystem productivity, and contributes to the buffering of atmospheric CO₂ concentrations.
