Cyanobacteria start producing pure oxygen around 200 million years ago.
<u>Explanation:</u>

They were very simple, but they produced oxygen in the early earth’s atmosphere. So, they brought evolution on earth. This “blue-green algae” exists in salt water, rocks and soils and play a major role in maintaining the ecosystem.
