Question

What are heterotrophic bacteria? Mention its types.

Answer 1

Heterotrophic bacteria are a type of bacteria that take the sugars they need to survive and reproduce from their environment, rather than making the sugars themselves from carbon and hydrogen. Bacteria that do produce their own sugars from carbon and hydrogen are called autotrophic.

Explanation:

Photoheterotrophs

Photoheterotrophs acquire energy from sunlight.

Photoheterotroph is the term used to describe bacteria that acquire energy from sunlight but require organic compounds like sugars from their environment to survive. Examples of photoheterotroph bacteria include heliobacteria, green non-sulfur bacteria and purple non-sulfur bacteria.

Chemoheterotrophs

Chemoheterotrophs can acquire energy from thermal vents.

Chemoheterotroph is the term used to describe bacteria that acquire energy from chemical reactions. Like all heterotrophs they require organic compounds to survive and cannot manufacture their own. Chemoheterotrophs are often found around thermal vents in the deep ocean.

Organotrophs

Hetero-organotrophs are involved in the composting process.

Organotroph is the term used to describe bacteria that acquire their energy from an organic substrate. Examples of hetero-organotrophs include the bacteria involved in composting.

Lithotrophs

Lithotrophs acquire energy from inorganic chemicals like iron.

Lithotroph is the term used to describe bacteria that acquire their energy from an inorganic substrate. Heterolithotrophic bacteria are very rare.
