All photosynthetic organisms create energy from sunlight.
the rise of photosynthetic
No, there are some photosynthetic protists and some photosynthetic bacteria.
The rise of photosynthetic organisms will not ever lead to a decrease in oxygen. The use of these organisms will always lead to an increase.
It would be impossible for oxygen requiring organisms to exist before photosynthetic organisms because there was not oxygen in the atmosphere for these organisms to breathe. Photosynthetic organisms take carbon dioxide and water in and create oxygen as waste. Before these photosynthetic organisms existed there was not enough or any oxygen in the atmosphere for organisms requiring oxygen to survive.

But I need this because I have a Science Life test Review and I can't answer {what are photosynthetic micro-organisms?}.

Why do plants and other photosynthetic organisms need CO2 from the atmosphere?
