Oxygen makes up about 21% of the Earth's atmosphere by volume. This level has been relatively consistent for the past few million years and provides the necessary amount of oxygen for humans and many other organisms to survive.
Yes, there is oxygen in the atmosphere of Mars, but it is present in very low concentrations, about 0.13%. This is much lower compared to Earth's atmosphere, which is around 21% oxygen.
Photosynthesis, which is the process by which plants and other organisms convert carbon dioxide and sunlight into oxygen and glucose, is responsible for producing much of the oxygen in Earth's atmosphere. This process is crucial in maintaining the balance of gases in the atmosphere and supporting life on our planet.
Oxygen makes up about 21% of the Earth's atmosphere.
Oxygen makes up about 21% of Earth's atmosphere. This level has remained relatively stable over long periods of time, supporting life on our planet.
Oxygen makes up about 21% of Earth's atmosphere by volume. This level has remained fairly consistent over millions of years due to the balance of oxygen-producing and oxygen-consuming processes in the environment.

the percentage of oxygen in the atmosphere today is about 20.95%. Or... if you round it you get the most common answer of 21%.
Oxygen makes up about 21% of the Earth's atmosphere.
Because too much oxygen is harmful to the environment.
Close to 21%, near 20.95%.
The atmosphere is 79.9% oxygen.
