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.

Unicellular,filamentous and photosynthetic organisms are ALGAE

But I need this because I have a Science Life test Review and I can't answer {what are photosynthetic micro-organisms?}.
Autotrophs
Why do plants and other photosynthetic organisms need CO2 from the atmosphere?
Lichen is considered to be a scavenger. They are commonly organisms that contain fungus and usually have a photosynthetic associate that they grow with.
Lichen is the product of a symbiotic relationship between a fungus and a photosynthetic organism, usually a photosynthetic bacteria or algae. The photosynthetic organism gains a place to live and protection. Most of the organisms that live as part of a lichen need a moist environment and cannot usually live in the areas that lichen can grow; The fungi allows the photosynthetic organism to remain moist. The fungi gains a source of energy from the photosynthetic organism. The photosynthetic organism produces sugars using solar energy which are used by the fungi.
