Does respiration decrease or increase the amount of carbon dioxide in the atmosphere?

Respiration (breathing) has no effect on the amount of carbon dioxide in the atmosphere. Breathing is part of the carbon cycle. We take in carbon in our food and drink and we release it again when we breathe. If we eat too much, the extra carbon is stored in our bodies, making us fatter, in much the same way as a tree stores carbon in its wood as it grows.So breathing does not increase or decrease the amount of carbon dioxide in the atmosphere.
