Oxygen---------- 4-5 %
Carbon dioxide---------- 20%
Nitrogen--------- 75%
Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
The four most abundant gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Nitrogen makes up about 78% of the atmosphere, oxygen around 21%, argon about 0.9%, and carbon dioxide less than 0.04%.
Carbon dioxide is a compound consisting of carbon and oxygen.
you breathe in more nitrogen then oxygen because there is 78% n in the air and 21% o in the air
The composition of standard dry atmosphere is: - nitrogen 78,084 % - oxygen 20,946 % - argon 0,934 % - carbon dioxide 0,039 % and extremely low concentrations of He, Ne, CO, Kr, Xe, Rn, CH4, O3.
The air that we breathe in 78% nitrogen, 21% oxygen, and 1% carbon dioxide, water vapor, and other gases. We only need the oxygen though, so we breathe out the other gases with the carbon dioxide that our body produces during respiration. So to answer your question, it is nitrogen, but we breathe it in and then out- we don't use it. The only gas we use is oxygen to breathe.
No, air is mostly nitrogen and oxygen with very very little carbon dioxide (less than 1%)What you exhale is mostly nitrogen, oxygen, and some carbon dioxide.
Carbon Dioxide. Actually you breathe in 78% Nitrogen so... Breathe in is to all sorts of gases.
Oxygen in, Carbon Dioxide out.Another answerBreathing breathes in the atmosphere: not the whole atmosphere obviously, but its composition. Breathing in occurs because of the necessity of oxygen-entrance and breathing out occurs because of the necessity of carbon dioxide-exit.The air consists of 79% nitrogen and 21% oxygen and 0.04% carbon dioxide and equally tiny percentages of other gases. We breathe in this 79% nitrogen and breathe out an equal percentage. We breathe in 21% oxygen and breathe out 16% oxygen. We breathe in 0.04% carbon dioxide and breathe out 4-5% carbon dioxide.
Yes, but in the form of carbon dioxide, with contains two atoms of oxygen and one of carbon. Cows don't breathe out the pure form of oxygen; they breathe in oxygen as well as nitrogen from the atmosphere.
The air we breathe out contains about 16% oxygen and 4% carbon dioxide. The rest is mainly nitrogen and trace amounts of other gases.
when you breathe in, you breathe in oxygen and when you breathe out, its carbon dioxide

Carbon dioxide is chemical compound. Oxygen and nitrogen are chemical elements.
Yes, people breathe in a combination of gases including nitrogen, oxygen, carbon dioxide, and others. Nitrogen makes up about 78% of the air we breathe.
We breathe in oxygen and breathe out carbon dioxide. Plants take in this carbon dioxide and release oxygen, which we use after that.
You breathe in oxygen.
