What process do scientists think provided earth with an oxygen-rich atmosphere?
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.
Do any of the planet have oxygen in their atmosphere?
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
What are he two main components of the atmosphere?
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.
What layer of atmosphere holds oxygen in earth?
the layer of the atmosphere that holds oxygen is the troposphere and its pause is tropopause
Did the atmosphere always have oxygen?
no
Does osmosis primarily release oxygen into the atmosphere?
No, photosynthesis. Oxygen is a byproduct of photosynthesis.
In what instance is a byproduct obtained?
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.
What element do cyanobacteria release to the atmosphereas a byproduct of the photosynthesis?
cyanobacteria releases oxygen as a byproduct into the atmosphere.
Why does oxygen occur naturally?
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.
What are the sources of atmospheric oxeygen?
The oxygen in the atmosphere is the result of biological activity. It is the byproduct of photosynthesis by plants.
What do they call the gas that enters the atmosphere during the light reaction?
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.
Why is there oxygen in the earth's atmosphere?
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.

Do plants take in carbon dioxide from the air?
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.
What releases oxygen into the atmosphere?
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.
What substance is the byproduct of photosynthisis?
There is only one byproduct. it is O2 gas.
Where did the gases in the earths atmosphere come from?
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)
