Question

What are heterotrophic bacteria?​

Answer 1

These are the type of bacteria that cannot prepare their own food, instead only obtains their food from the source of dead organic matter or living organisms.

Answer 2

Heterotrophic cells must ingest biomass to obtain their energy and nutrition. In direct contrast, autotrophs are capable of assimilating diffuse, inorganic energy and materials, and using these to synthesize biochemicals. Green plants, for example, use sunlight and simple inorganic molecules to photosynthesize organic matter. All heterotrophs have an absolute dependence on the biological products of autotrophs for their sustenance—they have no other source of nourishment.
