Yes, oxygen makes up 20.9% of the atmosphere.
The CO2 is absorbed through the blades and converted into carbon which is used in the growth of the blades and roots, and oxygen which is partly used in growth and partly released through the blades into the atmosphere.
The abundance of oxygen in Earth's atmosphere is primarily due to photosynthesis, a process carried out by plants and algae that produces oxygen as a byproduct. Without photosynthesis, oxygen levels in the atmosphere would decrease over time due to various processes that consume oxygen.
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
No, there is no oxygen in Mercury's atmosphere because Mercury does not have an atmosphere.
From the air largely and partly from its on metabolism
About 21% of the Earth's atmosphere is oxygen.
Plankton gives more oxygen to the atmosphere.
Animals remove oxygen from the atmosphere.
Cyanobacteria make molecular oxygen in our atmosphere.
Earth's atmosphere is about 21% oxygen by volume (for dry air).
