Air is 78% Nitrogen
There is 78% of nitrogen and 21% of oxyegen.
78% 0of the air we breathe is nitrogen, same as the amount in the air.
Gaseous nitrogen is harmless to animals. We breathe a lot of in normal air. Of course, if all you breathe is nitrogen, you will die from lack of oxygen.
While our bodies do need some nitrogen, we do not obtain this from the atmosphere. Environmental nitrogen exists in a form that can't be metabolized into the correct molecules (eg. urea/amino acids). That must be obtained from nitrogen-containing compounds that we eat.Nitrogen in the air (N2) is not reactive. It is a stable molecule that has a triple bond, therefore it won't react with anything in your body when you breathe it in.
because the haemoglobin present in our blood has no capacity to absorb nitrogen so the result is that the nitrogen is not absorbed and you breathe out the same amount of nitrogen as you breathed in.......

None! However, about 78% of what we breathe in and out is nitrogen.
You breathe in about 78 percent nitrogen. The amount that you breathe in varies.

It reduces the oxygen in the area because humans breathe in oxygen and breathe out nitrogen.[plants breathe in nitrogen and breathe out oxygen for humans.so without trees.Humans will not survive
Oxygen---------- 4-5 % Carbon dioxide---------- 20% Nitrogen--------- 75%
you breathe in more nitrogen then oxygen because there is 78% n in the air and 21% o in the air
The same one you breathe in the most, Nitrogen.
