How to heterotrophic bacteria obtain energy.

Autotrophs make their own food while heterotrophs consume organic molecules originally produced by autotrophs. By consuming other organisms expropriating their collected energy. One of the biggest differences between autotrophs and heterotrophs is that autotrophs have chlorophyll. Heterotrophic bacteria heterotrophic cells must ingest biomass to obtain their energy and nutrition.

From wikipedia article heterotroph. How do heterotrophs obtain energy. In direct contrast autotrophs are capable of assimilating diffuse inorganic energy and materials and using these to synthesize biochemicals. A heterotroph is an organism that eats other plants or animals for energy and nutrients.

Technically the definition is that autotrophs obtain carbon from inorganic sources like carbon. Chemotrophs are organisms that obtain energy by the oxidation of electron donors in their environments. Using chlorophyll plants as well as algae and various bacteria etc are able to trap light energy and use it to produce food. The term stems from the greek words hetero for other and trophe for nourishment.

A heterotroph ancient greek ἕτερος héteros other plus trophe nutrition is an or. Green plants for example use sunlight and simple inorganic molecules to photosynthesize organic matter. These molecules can be organic chemoorganotrophs or inorganic chemolithotrophs the chemotroph designation is in contrast to phototrophs which use solar energy chemotrophs can be either autotrophic or heterotrophic. These bacteria get their nutrients and generate energy from the organic compounds.

Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients. Heterotrophs cannot synthesize their own food and rely on other organisms both plants and animals for nutrition. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light photosynthesis or chemical energy chemosynthesis. Pathogenic bacteria belong to this group.
