When sugar in broken down in animals, either aerobically(with oxygen) or a aerobically(without oxygen), carbondioxide is released with either water vapour(for aerobic respiration) or with alcohol (for anaerobic respiration)

CO2 can't be added to the atmosphere by the build of organic compounds because plants use it in the build up, it is only released after cellular respiration which corresponds to C
