Plankton gives more oxygen to the atmosphere.
No it isn't. We still have about 21% oxygen content in the atmosphere.
Yes plants use photosynthesis to produce more oxygen, and also oxygen in rocks can escape to the atmosphere.
No. Earth's atmosphere is a mixture, mostly comprised of nitrogen and oxygen.
Algae and later plants used sunlight to convert water and carbon dioxide into carbohydrates and oxygen. Until about the middle of the Paleozoic oxygen went into the atmosphere faster than it could be removed.
the atmosphere is made of carbon dioxide and other gases e.g. oxygen and carbon dioxide
Plants gives us most of our oxygen in the atmosphere.
Nitrogen is more in the atmosphere. Around 78% of the atmosphere is nitrogen gas and 21% is oxygen gas.
This layer of the atmosphere is troposphere.
Yes, the earths atmosphere has around 20% oxygen, but less than 1% argon.
Nitrogen
Photosynthesis consumes carbon dioxide from the atmosphere, and releases oxygen.
The more oxygen there was the more it evolve.
Nitrogen
actually, more at night
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
