An autotroph is organisms that are able to make its own food. Autotrophic organisms take inorganic substances into their bodies & transform them into organic nourishment. Autotrophs are very essential to all life because they are the primary producers at the base of all food chains. There are 2 categories of autotrophs, distinguished by the energy each uses to synthesize food. Chemoautotrophs use chemical energy, Photoautotrophs use light energy
Autotrophic bacteria can produce their own food. "Auto" means "self" and "troph" means "nourishment." 5 common types of autotrophic bacteria are cyanobacteria, purple bacteria, green sulfur bacteria, methanogens & halophiles.
