How do plant and animals maintain the level of oxygen in the atmosphere?

Plants make oxygen and animals use oxygen. Over a couple of billions years, this system has stabilized so that oxygen makes up not quite 1/4 of the air you breath.
By far, the most oxygen-producing plants live in the oceans, and include algae, seaweed (See 'Sargasso Sea'), and other similar plants.

How the amount of oxygen in the atmosphere affects respiration?
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.
How do plants and animals mantain the level of oxygen in the atmosphere?
Animals breathe in oxygen and let out carbon dioxide. Plants take in carbon dioxide and release oxygen.
What is an oxygen enriched environment?
Air is the mixture of gases that surrounds the Earth. The composition of the earth's atmosphere varies with altitude, but at sea level contains approximately 78% nitrogen and 21% oxygen by volume.An oxygen-deficient atmosphere contains less than 19.5% oxygen by volume.An oxygen-enriched atmosphere contains more than 23.5% oxygen by volume.
How did the evolution of photosynthetic prokaryotes affect the level of oxygen in the atmosphere?
Photosynthesizing prokaryotes affected the ancient atmosphere by adding oxygen. In ancient times the oxygen level was .42%, compared to the 21% oxygen level now. Photosynthesizing prokaryotes have made the world livable today.
What is percentage of oxygen at sea level?
no; oyxgen levels are the amount of oxygen in the air where as sea level is a reference point for people to get a good idea of how tall of how low something is

How can you maintain oxygen in the atmosphere?
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.
How do plants and animals mantain the level of oxygen in the atmosphere?
Animals breathe in oxygen and let out carbon dioxide. Plants take in carbon dioxide and release oxygen.
Is oxygen part of the atmosphere?
Yes, molecular oxygen makes up about 20% of the atmosphere at sea level.
Why does the nitrogen level in the atmosphere is higher than the oxygen level?
Because due to the over pollution and cutting down the tree's level of Oxygen is decreasing .The level of Nitrogen always remains constant in the atmosphere . The level of Nitrogen doesn't' depend on the level of the Oxygen level.
What is the effect of sunlight on vegetable?
due to the present of sunlight photosynthesis is take place and its help to growth plant themselves and help to give oxygen to animals, maintain the oxygen level to environment.
What happen when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?
when higher energy ultraviolet radiation act on the oxygen at the higher level of the atmosphere, they destroying many molecules of atmosphere.
How long has the oxygen concentration of the atmosphere been at its current level?
The oxygen concentration in the atmosphere today (which is at about 21%) has been at its current level for the past 400 million years.
What is the Level of oxygen on Saturn?
There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.
Atmosphere in the permian?
the atmosphere in the Permian had 115 % of modern oxygen level and 3x the amount of carbon dioxide- pre-industrial level.
Does the troposphere have oxygen?
Oh yes. The troposphere is the lowest level of the atmosphere, the level that we live and breathe in, and it does have lots of oxygen in it, until you get to very high altitudes.
Where in atmosphere does meteoroids burn?
"where the oxygen level increases then combustion takes place"
