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.
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.
the air
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.
This oxygen is sourced from plants through the process of photosynthesis, where they take in carbon dioxide and release oxygen as a byproduct.
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.
Plants
Yes.
I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.
is it oxygen
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
Photosynthesis is the source of virtually all the free oxygen in the earth's 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.
