Nitrogen, N2 and oxygen, O2
The same gasses that comprise regular air: nitrogen, oxygen, carbon dioxide, water vapor, and trace amounts of others.
Besides the gases that comprise air, air can also contain variable amounts of water vapor -- characterized by the term, "relative humidity." Because the amount of water vapor held in air can change, it is simpler and more sensible to express component gas percentages on the basis of dry air. Type your answer here...
What percentage of gases do we breath in
To present a pie chart showing the gases in air, you can divide the chart into sections representing the percentage of each gas in the air composition. Label each section with the name of the gas and its corresponding percentage. Displaying the relative sizes of the sections will visually represent the composition of gases in air.
They reduce CO2 and increase O2.

Oxygen, Nitrogen and Argon comprise 99% of the air.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
The most abundant gases in air by weight are nitrogen (78%) and oxygen (21%). Other gases like argon, carbon dioxide, and traces of other gases make up the remaining percentage of the air's composition.
The air you breathe out contains around 16% oxygen and 4% carbon dioxide, with the remaining percentage made up of nitrogen, water vapor, and other trace gases.
In the air around us there is 78% nitrogen 21% oxygen 1% other gasses
