], respiration [respiration: Chemical change that takes place inside living cells, which uses glucose and oxygen to produce the energy organisms need to live. Carbon dioxide is a by-product of respiration ] and combustioncombustion: Combustion is the process of burning by fire.. Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms - including all plants and animals - release energy from their food using respiration. Respiration and combustion - burning - both release carbon dioxide into the atmosphere.
This carbon dioxide can be released into the atmosphere and ocean through volcanoes and hotspots. It can also be removed by humans through the direct extraction of kerogens in the form of fossil fuels.After extraction, fossil fuels are burned to release energy, thus emitting the carbon they store into the atmosphere.his carbon dioxide can be released into the atmosphere and ocean through volcanoes and hotspots.
