Energy Capture by Prokaryotes
| Mode of Nutrition | How Energy is Captured | Habitat | Example |
|---|
| Heterotroph"other feeder" | Take in organic molecules from environment or other organisms to use as both energy and carbon supply. | Wide range of environments | Clostridium |
| Photoheterotroph"light and other feeder" | Like basic heterotrophs, but also use light energy | Where light is plentiful | Rhodobacter, Chloroflexus |
| Photoautotroph"light self-feeder" | Use light energy to convert Carbon dioxide into carbon compounds | Where light is plentiful | Anabaena |
| Chemoautotroph"chemical self-feeder" | Use energy released by chemical reactions involving ammonia, hydrogen sulfide, etc. | In chemically harsh and/or dark environments: deep in the ocean, in thick mud, in digestive tracts of animals, in boiling hot springs | Nitrobacter |
