Photosynthetic organisms, also known as photoautotrophs, are organisms that are capable of photosynthesis. Some of these organisms include higher plants, some protists (algae and euglena), and bacteria.
Two factors infuence the regions photosynthetic productivity which would be the amount of solar radiation and the availability of nutrients because solar radiation is needed as well as nutrients which keeps the plant healthy
hope this helps (:
