The most important component of the air you breathe is oxygen. Oxygen is essential for the process of respiration, where it is used by your body to generate energy. Without oxygen, your cells would not be able to function properly.
Nitrogen and oxygen are the two most abundant gases in the air. They are actually elements and not compounds. The two most abundant compounds would be water vapor and carbon dioxide.
This gas is oxygen - 20,946 %.
100% Nitrogen, 321% oxygen, 1% Argon and Carbon Dioxide. The four most common gases in dry air consist of nitrogen, oxygen, argon, and carbon dioxide. Nitrogen and Oxygen make up most of dry air.
Air is rich in nitrogen, oxygen, and other gases such as argon, carbon dioxide, and water vapor. Oxygen is the most abundant element in the Earth's atmosphere, making up about 21% of the air we breathe.
Plants release oxygen into the atmosphere as a by-product of photosynthesis.
Oxygen! AKA: The air we breathe.

Oxygen (O2) is released back into the air after photosynthesis occurs.
Plants take in carbon dioxide. Oxygen is released as a gas.

Oxygen is the second abundant gas in the air-mixture: about 19% by volume. Nitrogen is more in air by 80% v/v
Most of autotrophic plants get major amount of oxygen from photosynthesis. During night, when there is no photosynthesis, oxygen by plants is obtained from air However, the amount of oxygen released during photosynthesis by plants is manifold of their requirement for respiration.
Oxygen is most commonly found in the air of Earths atmosphere.
