A producer (e.g. a plant) is an organism with chloroplasts. An organism with chloroplasts is a photosynthetic organism. Plants and algea have chloroplasts while some protists also have them.
cyanobacteria releases oxygen as a byproduct into the atmosphere.
Probably ancient cyanobacteria.
Cyanobacteria, which are sometimes incorrectly called blue-green algae, were the first organisms to add oxygen to early Earth. Blue-green algae are eukaryotes while cyanobacteria are the much earlier prokaryotes.
Cyanobacteria, also called blue-green algae, are bacteria that photosynthesize but do not have chloroplasts.
Prokaryotic organisms have no nucleus. This includes all bacteria, including the archea and cyanobacteria.
