the air is a mixture mainly of Nitrogen, around 80%, and a mixture of other gases including Oxygen and Carbon Dioxide (CO2). Only the oxygen is required for human breathing purposes, so you take in about 5 times the quantity of air as you need in order to get your oxygen supply. When the oxygen is used for 'internal combustion by the body's muscles, the by product is carbon dioxide which becomes part of the air you breath out.
Plants don't actually breath but absorb CO2 in the process of photosynthesis, which requires light to operate, at which point the plant will release oxygen, but during the dark hours, it uses oxygen and puts out CO2.
