Discuss about autotrophic bacteria and heterotrophic bacteria.
- Heterotropic bacteria- obtain energy from organic molecules.
- Autotrophic bacteria- make their own food by converting light energy, chemical energy or inorganic substances into food.
1) Chemoautotrophs- are autotrophic bacteria which obtain their nutrition from inorganic compounds.
2) Photoautotrophs- are autotrophic bacteria that absorb light energy to carry out photosynthesis to create cellular energy.
