Looking only at the components of the dry atmosphere (everything but the water vapor, which varies), oxygen accounts for 21 percent. It is 16 percent of the air you exhale.
the outcoem will rise as well but in the GDP will stay at the same level
Multicellular algae is crucial to the atmosphere, as it actually produces the greatest percentage of oxygen in our atmosphere, compared to other photosynthetic organisms.
The amount of oxygen you get with every breath at the peak of Everest is about 1/4 of what you get at sea level. At sea level, oxygen is about 21% of the gas you breathe. I don't know if that percentage changes with altitude.
Percentile is not exactly percentage. 73.6 percentile means that, compared to some set, your score (height, intelligence, weight, etc. - whatever you are talking about) is at the 73.6 percent level - 73.6 percent of the population that is being considered has a lower score.
As there is a low level of carbon dioxide in the air that animals (and people) breath, yes every breath taken in breaths in some carbon dioxide.But as carbon dioxide in the blood is transferred to the air in the lungs, increasing the level of carbon dioxide in that air, when they breath out both the carbon dioxide breathed in and the additional carbon dioxide from the blood are breathed out. Thus in balance more carbon dioxide is breathed out than is breathed in.
At 7200 feet, the oxygen level is lower compared to sea level because the air pressure is reduced at higher altitudes. This decrease in oxygen level can lead to symptoms of hypoxia such as shortness of breath, fatigue, and dizziness.
The percentage is called blood alcohol level. This level should not exceed a certain limit, or you loose consciousness. This level may change from person to person.

Level of performance is the attained level which a person or organization has reached compared/relating to the set goals and standard.
When the price level and the money wage rate change by the same percentage, the real wage rate remains constant at its full employment equilibrium level so employment remains constant and real GDP remains constant at "potential GDP" which is the quantity of real GDP at full employment.
Nothing, you just stay on that level.
The ground level ozone is a pollutant. However it also causes large number of problems. Skin irritation, lung infection etc are some serious problems caused by it.
