Oxygen makes up 21% of the Earths atmosphere.
The percent of the atmosphere made out of carbon dioxide is 0.038.
Oxygen forms less than 1% of the atmosphere but is essential for life as it is required for cellular respiration in organisms to produce energy.
Oxygen makes up about 21 percent of the Earth's atmosphere. It is essential for the respiration of most living organisms and plays a crucial role in various chemical processes, including combustion. Oxygen is produced primarily by plants during photosynthesis.
21% of the atmosphere is oxygen.
When it comes to world organisms, there are four main groups. These groups are then classified into smaller percentages of groups. For the main four groups 25 percent are bacteria, 30 percent are protists, 40 percent are green plants, and 5 percent are classified as fungi.

Oxygen composes of twenty-one percent of Earth's Atmosphere.
Nitrogen is nearly 78 percent of the earth's atmosphere.
There is no such planet in our solar system. Perhaps you meant the atmosphere of the planet. The Earth has an atmosphere that's mainly nitrogen
