Summary:
- Prokaryotes have just about every possible type of metabolism.
- They depend on other organisms for both energy and carbon.
- They may get energy from light (photo) or chemical compounds (chemo) They may also get carbon from carbon dioxide (autotroph) or other living things (heterotroph).
- Most prokaryote are chemoheterotrophic, but they can be photoautotrophic or chemoautototrophs, as well as heterotrophic and autotrophic.
