What organisms, besides green plants, are producers?

Producers are biological organisms that produce organic ones from inorganic substances. The word itself is translated from Latin as “creating, producing”. For example, thanks to photosynthesis, oxygen is released into the atmosphere, which is produced by all green plants. In addition to them, bacteria are also producers: cyanobacteria (also produce oxygen with the help of the sun) and chemosynthetics (they oxidize inorganic substances (sulfur, iron) and do not need solar energy) ).
