Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
Plankton gives more oxygen to the atmosphere.
No it isn't. We still have about 21% oxygen content in the atmosphere.
No. Earth's atmosphere is a mixture, mostly comprised of nitrogen and oxygen.
the atmosphere is made of carbon dioxide and other gases e.g. oxygen and carbon dioxide
About 1/5
None of them that we know of because they don't have oxygen. We could live on Mars if we install an artificial atmosphere and maintain millions of plants inside it to keep oxygen in.
Plants They take in carbon dioxide Then keep the carbon to grow and give out oxygen
fairly constant
The atmosphere is 79.9% oxygen.
21% of the atmosphere is oxygen.
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
The moon has no oxygen because it has no atmosphere.
Yes, oxygen makes up 20.9% of the atmosphere.
Cyanobacteria make molecular oxygen in our atmosphere.
Plankton gives more oxygen to the atmosphere.
Animals remove oxygen from the atmosphere.
