Which autotrophs are better and why?

Autotrophs are organisms that are able to obtain organic substances from inorganic ones, thereby obtaining food for themselves and for others “out of nothing”. These miraculous organisms include plants and cyanobacteria. These organisms can use the energy of the sun, in their special organelles containing the pigment chlorophyll, to form glucose and oxygen, which we breathe. Therefore, these organisms determine the existence of life on our planet, and make an invaluable contribution. Therefore, it is difficult to determine which autotroph is better and why, they are all very important in nature.
