autotrophic prokaryotes enriched the atmosphere with oxygen in the precambrian era :) hope this helps
Photosynthesizing prokaryotes affected the ancient atmosphere by adding oxygen. In ancient times the oxygen level was .42%, compared to the 21% oxygen level now. Photosynthesizing prokaryotes have made the world livable today.
Most of the worlds oxygen is produced by Trees.
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
Cyanobacteria, which are sometimes incorrectly called blue-green algae, were the first organisms to add oxygen to early Earth. Blue-green algae are eukaryotes while cyanobacteria are the much earlier prokaryotes.
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.
autotrophic prokaryotes!

Life on earth depend upon metabolic diversity of prokaryotes because Prokaryotic photosynthesis provides free oxygen in the atmosphere
The rapid rise of atmospheric oxygen illustrated in the geological record by layers of iron oxides.
They are: a) Oxygen b) Water
Yes
Oxygen....
The first living cells had to be autotrophic because if they were not then they would die, autotrophic bacteria produce oxygen and can live in our older Earth's climate. Any other would die from a lack of oxygen.
Yes, as oxygen is one of the products of the photosynthetic process. Water is " cracked " to provide electrons for the chlorophyll pigment as a replacement process and the oxygen is released from H2O and goes back into the atmosphere through the stomata.
yes it is autotrophic
Most of the worlds oxygen is produced by Trees.
The atmosphere is 79.9% oxygen.
