• Almost all eukaryotes are either photoautotrophic
  (e.g. plants and algae) or chemoheterotrophic
  (e.g. animals, protozoa, fungi).
• Lithotrophy is unique to prokaryotes and
  photoheterotrophy, common in the Purple and Green
  Bacteria, occurs only in a very few eukaryotic
  algae.
• Phototrophy has not been found in the Archaea,
  except for nonphotosynthetic light-driven ATP
  synthesis in the extreme halophiles.
