About 16% of the air you expel is oxygen.
Oxygen is approximately 21% of the air we breathe.
you breathe in more nitrogen then oxygen because there is 78% n in the air and 21% o in the air
No it isn't. It is Nitrogen, which makes up 70% of the air we breathe.
78% of the air we breathe is nitrogen. 21% is oxygen, and the other 1% is a mix of other gasses.
The oxygen content in the ocean is lower than the air humans breathe. The ocean contains less oxygen because it is not constantly replenished like the air on land, which is continuously refreshed by plants through photosynthesis.
Oxygen is approximately 21% of the air we breathe.
Around 21% of the air you breathe is oxygen.
The air you breathe out contains less oxygen because your body extracts oxygen from the air when you breathe in and uses it during cellular respiration to produce energy. As a result, the air you breathe out has a higher concentration of carbon dioxide and less oxygen.
Typically, the air you breathe is comprised of 18 to 21 percent Oxygen.
You blow out carbon dioxide, trees breathe it in, trees breathe out oxygen, you breathe in oxygen. It's the air cycle.
You blow out carbon dioxide, trees breathe it in, trees breathe out oxygen, you breathe in oxygen. It's the air cycle.
About 21% of the air we breathe is oxygen. The other major components are nitrogen (about 78%) and trace gases like argon, carbon dioxide, and others.
On average, humans breathe in about 21% oxygen from the air.
Oxygen makes up about 21% of the air we breathe.
The air we breathe out contains about 16% oxygen and 4% carbon dioxide. The rest is mainly nitrogen and trace amounts of other gases.
