The source of oxygen in the atmosphere is a complicate stellar process.
Oxygen was introduced into the atmosphere as a byproduct of photosynthesis.
The oxygen has been there for millions of years. It is replenished by the action of plants.
Photochemical Reactions
Photosynthesis
Oxygen is a byproduct of photosynthesis.
Photosynthesis in plants and algae
trees Plants, like trees and flowers.
the correct answer is photosynthesis
volcanic eruptions
Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen.
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
The two major components of the earth's atmosphere are nitrogen and oxygen. There is also trace amounts of hydrogen, carbon dioxide, and other gases.
the layer of the atmosphere that holds oxygen is the troposphere and its pause is tropopause
no
No, photosynthesis. Oxygen is a byproduct of photosynthesis.
A byproduct is basically something which is produced that the plant does not need for it self. For example, When a plant photosynthesizes, it releases most of the oxygen as a byproduct into the atmosphere.
cyanobacteria releases oxygen as a byproduct into the atmosphere.
It is a byproduct of the life processes on Earth. Earth's early atmosphere contained no Oxygen, but Earth was slowly Terra-formed by life and obtained an Oxygen rich atmosphere.
The oxygen in the atmosphere is the result of biological activity. It is the byproduct of photosynthesis by plants.
The gas that enters the atmosphere during the light reaction is oxygen (O2). Oxygen is produced as a byproduct when water is split during photosynthesis.
The oxygen is the product of photosynthesis. Plants and algae use the energy of sunlight to turn water and carbon dioxide into sugar and oxygen. The plants use the sugar as food and turn some into cellulose to make cell walls. Oxygen is released into the atmosphere as a byproduct.

Plants take in carbon dioxide from the atmosphere to use in the dark reactions (Calvin Cycle) of photosynthesis, and oxygen is released into the atmosphere as a byproduct of photosynthesis.
Plants, especially through the process of photosynthesis, release oxygen into the atmosphere. Photosynthesis involves the absorption of carbon dioxide and the release of oxygen as a byproduct. Additionally, certain types of algae and cyanobacteria contribute to oxygen production through photosynthesis in aquatic environments.
There is only one byproduct. it is O2 gas.
Scientist theorize that bacteria with chlorophyll in them slowly but surely began to multiply. And as they did, they photosynthesized enough to create an entire atmosphere. (as you know oxygen is a byproduct of photosynthesis)
