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%
No. Carbon dioxide is a chemical compound of carbon and oxygen.
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), argon (0,934 %), carbon dioxide (0,0314).
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
No, carbon dioxide does not contain oxygen in its composition. Carbon dioxide consists of one carbon atom and two oxygen atoms bonded together.
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.
