Carbon respiration Carbon respiration Carbon respiration (also called carbon emissions and carbon releases) is used in combination with carbon fixation to gauge carbon flux (as CO) between atmospheric carbon and the global carbon cycle Carbon is released to the atmosphere through the burning of fossil fuels, organic respiration, wood burning, and volcanic eruptions. The uptake of carbon from the atmosphere occurs through carbon dissolution into the oceans, Photosynthesis, and the consequent storing of carbon in various forms such as peat bogs, oil accumulation, and formation of minerals such as coal and copper. It also happens when carbohydrates are changed into carbon dioxide.
Carbon dioxide to extinguish flames by flooding the environment around the flame with the gas. It does not itself react to extinguish the flame, but starves the flame of oxygen by displacing it. Some fire extinguishers, especially those designed for electrical fires, contain liquid carbon dioxide under pressure. Carbon dioxide extinguishers work well on small flammable liquid and electrical fires, but not on ordinary combustible fires, because although it excludes oxygen, it does not cool the burning substances significantly and when the carbon dioxide disperses they are free to catch fire upon exposure to atmospheric oxygen. Their desirability in electrical fire stems
