Plants
The primary source of Earth's atmosphere is outgassing from volcanic activity and the release of gases from Earth's interior. This process began billions of years ago and continues to contribute to the composition of our atmosphere.
Oceans
Oxygen in Earth's atmosphere was produced through the process of photosynthesis by cyanobacteria and early algae, starting around 2.5 billion years ago. These organisms converted carbon dioxide and water into glucose and oxygen using sunlight as an energy source. This oxygen began accumulating in the atmosphere and eventually led to the development of the oxygen-rich atmosphere we have today.
Green Plants
Volcanic activity was the primary source of CO2 in the Earth's early atmosphere. During this time, volcanic eruptions released large amounts of gases, including carbon dioxide, into the atmosphere.

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.
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.

I! think the most aboundant element on earth should be oxygen, because it is the only source of life through which we breath in.
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
