CO2 (Carbon Dioxide) for the most part, but the components of the original air that was inhaled are still present, although the O2 (oxygen) component will be reduced.
humans give off a stinky gas from their lower region.
Carbon dioxide and methane
Carbon Dioxide aka CO2
methane
Carbon dioxide
Photosynthesis results in the release of oxygen in the air. It becomes the oxygen that we humans, and other organisms, inhale for cellular respiration.
oxygen
Plants release oxygen into the atmosphere as a by-product of photosynthesis.
I think carbon dioxide but definitely a bowel gas which can be deadly sometimes
Basically by burning things like coal, oil and natural gas (fossil fuels).
Oxygen
no. Cows make Methane gas (poop) which is a greenhouse gas. However dirty,stinky humans are the major causes of air pollution.

there would have to be air on Jupiter and there is not its all gas
