Ambient air (the air you breathe in) contains about 21% oxygen and about 380 ppm carbon dioxide. This changes slightly summer to winter, downwind of green vegetation during the day and in buildings.

Because your body consumes the oxygen and generates carbon dioxide as a waste product. Extracting oxygen and emitting carbondioxid is what the lungs are for.
Oxygen---------- 4-5 % Carbon dioxide---------- 20% Nitrogen--------- 75%
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), argon (0,934 %), carbon dioxide (0,0314).
No. Carbon dioxide is a chemical compound of carbon and oxygen.
Carbon dioxide is a compound consisting of carbon and oxygen.
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
Oxygen-Carbon Dioxide Cycle- a continuous exchange of oxygen and carbon dioxide by plants and animals including human
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.
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
No, carbon dioxide does not contain oxygen in its composition. Carbon dioxide consists of one carbon atom and two oxygen atoms bonded together.
