Cyanobacteria, also known as cyanobacteria, belong to prokaryotes, so only ribosomes, organelles without chloroplasts and mitochondria, contain chlorophyll and can be used for photosynthesis. Metabolic type belongs to autotrophic aerobic type, and the process of aerobic respiration is completed in cytoplasmic matrix.

Some organisms are chemically autotrophic, for example, some volcanic lava is surrounded by many bacteria, and they are autotrophic through chemical reactions in an anaerobic environment. Of course, in some cases.

Which is aerobic breathing.
