The main source of atmospheric oxygen, on Earth, is cyanobacteria (aka "blue-green algae") in the ocean. According to NASA, it is responsible for 90% of the conversion of CO2 (carbon dioxide) into O2 (oxygen) that we breath.
Most of the other 10% is converted by other forms of algae, and saltwater/freshwater plants in general. Land plants actually do not produce enough O2 to even make up for the amount consumed by the bacteria and chemicals among their own roots.
Cyanobacteria, regular algae, and plants all do their conversion of carbon dioxide into oxygen using a process called "photosynthesis", in other words the creation (synthesis) of energy (sugars) from light (photo). Higher order plants do this by actually hosting a sort of cousin of cyanobacteria (called chloroplasts) in their own cells.
Photosynthesis is the main source of atmospheric oxygen; but some may come from water vapour being split into oxygen & hydrogen by ultraviolet radiation.

Which atmosphere gas is photosynthesis the major source of?
oxygen
True or false red blood cells carry oxgen to the rest of the body?
true
When a carbon atom enters the atmosphere it turns into what?
it should still be carbon, but too much carbon is bad for the atmosphere. Google: "Carbon in atmoshpere" and see why it's bad
How much of earth's atmosphere is composed of nitrogen gas?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
What is the final acceptor of hydrogen in a cellular respiration?
Molecular Oxygen, otherwise known as O2.
What gas was missing from earth's early atmosphere?
probably oxgen
What are three things must be present to produce a fire?
Oxgen, Fuel and a heat source
How is oxgen from the atmosphere important?
It is important because without it, there can be no living thing. Living organisms need oxygen to exist.
How much percent of your brain is oxgen?
None, if your dumb
Is there oxgen on Mount Everest?
yes but not as much because the air is thiner
What is a plants source of carbon dioxide?
Plants and animals are both complex organisms that share in a cycle of carbon dioxide and oxygen. Animals breathe out carbon dioxide when they respirate and plants take that in through their leaves and then emit oxgen which animals inhale. And the cycle begins again.
Where oxgen is found?
Oxygen is found in many places. Some examples are: The earth's crust The ocean The atmosphere Inside stars In your lungs. Hopefully I answered your question.
The is the source of all energy in our atmosphere.?
The source of all energy in our atmosphere is the sun.Some energy is reflected back into space, some is absorbed by the atmosphere, some is absorbed by land and water on Earth's surface (all of the above) When Earth receives energy from the Sun.
Why is your cabrio 2002 using so much gas?
Change your oxgen Sensors and plugs. This is what worked for me.
What is the other source of calcium?
the atmosphere
What is the source of energy for our atmosphere?
The Sun.
What is the source of radiation for both the Earth's atmosphere and the greenhouse?
Sol.The Sun is the source of radiation for both the earth's atmosphere and the greenhouse effect.
