How did photosynthesis change the atmosphere

WebWhile photosynthetic life reduced the carbon dioxide content of the atmosphere, it also started to produce oxygen. For a long time, the oxygen produced did not build up in the atmosphere, since it was taken up by rocks, as recorded in Banded Iron Formations (BIFs; picture) and continental red beds. WebFour billion years ago, Earth’s atmosphere had little or no free oxygen. That changed when bacteria evolved the ability to photosynthesize, which releases oxygen as a byproduct. For example, the first jump in Earth’s oxygen levels may have been triggered by the proliferation of photosynthetic bacteria in the oceans.
