sergiy2304 [10]

Given what we know, we can confirm that the significant increase in oxygen in the Earth's atmosphere 2 to 2.5 billion years ago is due to cyanobacteria.

<h3>What are cyanobacteria?</h3>

These are tiny bacterial organisms. They were amongst the first organisms to use photosynthesis to sustain life. The sudden boom of cyanobacteria accounts for the rapid increase in oxygen given that they will use carbon dioxide to produce sugar through photosynthesis, expelling oxygen in the process.
