Question

Are chemosynthetic bacteria-autotrophic or heterotrophic?

Answer 1

Autotrophs

Autotrophs are organisms that have the ability to make their own food using solar energy or energy from certain chemicals.

Heterotrophs

Heterotrophs are organisms that derive nutrition from dead, decaying organisms (saprophytes) or living organisms (parasites).

Chemosynthetic bacteria

Chemosynthetic bacteria are a group of autotrophic bacteria that use chemical energy to produce their own food.
Example: Methanogens
