The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere
The atmosphere is 79.9% oxygen.
The moon has no oxygen because it has no atmosphere.
The atmosphere has the same amount of oxygen today as it did 1000 years ago. Although oxygen gets used up in various ways, through fire and through metabolism, oxygen is constantly being released into the atmosphere by green plants.
Plants gives us most of our oxygen in the atmosphere.
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere
The oxygen in water is the oxygen that is released into the atmosphere.
Oxygen! :)
Oxygen.
CFC's are released into atmosphere. They break the ozone into oxygen molecules.
The amount of oxygen released into the atmosphere has not noticeably increased in recent years. The amount of oxygen (O2) in the atmosphere is about 21%. It is part of the earth's oxygen cycle, the main driver of which is photosynthesis. Vegetation removes carbon dioxide (CO2) from the atmosphere, releases the oxygen (O2) and stores the carbon (C).
Carbon dioxide is being released. As you breathe in you inhale fresh oxygen, but as you breathe out your body releases carbon dioxide.
It gets released into the Atmosphere.
Photosynthesis
Plants release oxygen into the atmosphere as a by-product of photosynthesis.
Plants produce an excess of oxygen which is released into the atmosphere. This is a product of photosynthesis.
It released into the atmosphere, if it isn't immeadiately used in respiration.
