Identifying Bacteria

• Shapes

  • bacilli: rod shaped
  • cocci: pherical
  • spirilla: spiral
• Methods of Obtaining Energy

  • Heterotrophs get their energy by consuming organic molecules made by other organisms
  • Autotrophs make their own food from inorganic compounds
  • Photoautotrophs use light energy to convert carbon dioxide and water to carbon compounds and oxygen
  • Chemoautotrophs preform chemosynthesis - they make organic carbon molecules from carbon dioxide, but doesn't require light as energy
