The nitrogen and oxygen in Earth's atmosphere together account for a speck more than 99% of it..
78% Nitrogen 21% Oxygen
atmosphere
Much less than the approximate 21% in the air. Perhaps half that. Fish need a large energy expenditure to strain oxygen from the water. Most of the oxygen produced by phytoplankton, for instance, is vented into the atmosphere.
The ratio is approxNitrogen : Oxygen : Argon : Carbon Dioxide :: 39000 : 10500 : 465 : 19.
Oxygen is replaced through the process of photosynthesis, where plants and other producers take in carbon dioxide and release oxygen as a byproduct. Additionally, oxygen is replenished by the dissolving of oxygen gas from the atmosphere into water bodies.
21% of the atmosphere is oxygen.
The atmosphere is 79.9% oxygen.
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
Oxygen in the air is constantly replenished through the process of photosynthesis, where plants take in carbon dioxide and release oxygen. This cycle helps maintain the balance of oxygen in the atmosphere.
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
Yes, oxygen makes up 20.9% of the atmosphere.
Plankton gives more oxygen to the atmosphere.
Cyanobacteria make molecular oxygen in our atmosphere.
Animals remove oxygen from the atmosphere.
About 21% of the Earth's atmosphere is oxygen.
Photosynthesis is carried on by plants that produce oxygen.This process has replaced all oxygen that is in the atmosphere for more than 2 000 years.
