Green plant life.
Carbon dioxide in absorbed by green plant leaf. It undergoes photosynthesis in the plant; the oxygen is released back into the atmosphere and the carbon is retained in the plant as biomass.
It is part of the Carbon / Oxygen cycle.
The primary source of Earth's oxygen is through the process of photosynthesis carried out by plants, algae, and cyanobacteria. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Additionally, a small amount of oxygen is produced through chemical reactions in the atmosphere.

What is a source of carbon and oxygen?
Plants are a primary source of carbon and oxygen through the process of photosynthesis, where they take in carbon dioxide from the air and convert it into glucose, releasing oxygen as a byproduct.
What is a Source of oxygen for a fire?
the air
Which group of organisms is the source of oxygen in the oxygen cycle?
Plants, algae, and cyanobacteria are the main producers of oxygen in the oxygen cycle through the process of photosynthesis. These organisms convert carbon dioxide and sunlight into oxygen and carbohydrates, sustaining the oxygen levels in the atmosphere.
What is the source of this oxygen?
This oxygen is sourced from plants through the process of photosynthesis, where they take in carbon dioxide and release oxygen as a byproduct.
Can chapstick and oxygen start a fire?
No, chapstick and oxygen alone would not be able to start a fire. A fire typically requires a fuel source, heat, and an ignition source. Chapstick is not flammable on its own, and oxygen is not combustible.
What is the major source of oxygen for the earths atmosphere is?
Plants
Is earths core a source of earths magnetic field?
Yes.
What is the most aboundant element in earths atmosphere?
I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.
Elements in the earths crust?
is it oxygen
How much of the earths atmosphere is made up of nitrogen and oxygen?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
Is most of the earths atmosphere covered with oxygen?
no
What percent of earths atmosphere is oxygen?
97%
Does the ocean help with the earths oxygen?
Yes
How did bacteria change early earths atmosphere?
Earth's early atmosphere was primarily composed of carbon dioxide. Early bacteria used carbon dioxide as a source of fuel and as a result produced oxygen.
What effect does photosynthesis have on the amount of oxygen in the atmosphere?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What is earths primary energy source?
sun
