The earths atmosphere is made up of 78% nitrogen and 21% oxygen
About 78% of it is nitrogen. Another 21% of the atmosphere is oxygen, and 1% are other gasses found in very small amounts.
About 70.1 per cent of the Earth's atmosphere is nitrogen.
This is the figure by volume for dry air.
Nitrogen accounts for 78% of the atmosphere.

In air there is 20.98% Oxygen, so that's what we inhale. We exhale 16% of this Oxygen; hence why cardiopulmonary resuscitation is possible.

Most plants absorb nitrogen from Nirates in the soil. A notable exception are insectivorous plants such as the Venus Fly Trap, which lives in soils which do not have much Nitrogen - so have adapted to obtain it from another source.
Rhizobia are bacteria found in soil that fix nitrogen once they're established inside the roots of legumes. This helps the plant obtain nitrogen more easily, and for these plants, it means that nitrogen fertilizer is not needed nearly as much.

The atmosphere of Mars is much less dense than that of Earth and is composed almost entirely of carbon dioxide. Earth's atmosphere is mostly nitrogen and oxygen.
I think because pluto is farther from the sun than earth the nitrogen is probally frozen so there is not as much and it is colder than the nitrogen found on earth
Assorted gases such as argon, the rest of the atmosphere is pretty much just Oxygen and Nitrogen.
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
About 78% of the atmosphere is nitrogen.
The Earth's atmosphere is approximately 79% nitrogen.
98% of Titan's atmosphere is Nitrogen
