Well to maintain the oxygen in the earth atmosphere you need to make sure that the level of global warming is decreasing and less fumes will be able to make up the ozone layer. With a thinner layer around the earth this means that oxygen will be able to enter and exit the earths surface, allowing oxygen to still stay in the atmosphere.
Green plants, as they carry out photosynthesis, are constantly releasing oxygen into the atmosphere.
The lower the percentage of oxygen air contains, the more frequent a breath must be taken in order to maintain the blood oxygen level at an acceptable level.
21% of the atmosphere is oxygen.
The atmosphere is 79.9% 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
The moon has no oxygen because it has no atmosphere.
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
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.
Frozen. Pluto is too small to maintain a gaseous atmosphere, and orbits so far from the Sun that any gasses would freeze out as oxygen or hydrogen snow.
forests absorb the carbon dioxide and help to maintain balance
Yes, oxygen makes up 20.9% of the atmosphere.
Plankton gives more oxygen to the atmosphere.
