Carbon cycle

visual representation

the carbon cycle

decomposition

dead organic matter is broken down by microorganisms called decomposers, releasing CO2 or CH4 as byproducts, returning nutrients to the environment

combustion

chemical reaction where a fuel reacts with oxygen, releasing heat and light, producing products like CO2 or water vapour

respiration

biological process where living organisms exchange gases (CO2 and O2) to produce energy through cellular respiration or to neleasewaste gases through breathing

dissolution

where carbon goes between the atmosphere and the hydrosphere (e.g. carbon sequestration and ocean acidification)

photosynthesis

process where plants/algae and some bacteria use sunlight, CO2 and water to produce energy (glucose) and release oxygen as a byproduct
