Question

How do chemo heterotrophs differ from chemoautotrophs ?

Answer 1

Hint: Chemotrophs are the organisms that utilise inorganic substances as energy source in place of sunlight which is used by phototrophs as the source of energy. Chemotrophy is exhibited by the organisms which live in deep and dark places where sunlight cannot reach. It is a very helpful mode of nutrition for many organisms which are mostly bacterias.

Complete answer:
Chemoautotrophs are organisms which use inorganic substances for energy, as electron donors and also a source of carbon. On the other hand, talking about chemoheterotrophs, they are the organisms which utilise organic substrates for the same purpose. Autotrophs are the organisms which assimilate organic substances from inorganic substrate wild heterotrophs are the organisms which utilizes the organic substrates produced by autotrophs as energy for carrying out various functions in their bodies.
Examples of chemoautotrophs are nitrosomonas nitrococcus nitrosococcus sulfurimonas.Some organisms which are chemoheterotrophs based on their mode of nutrition are fungi etc. The oxidation of some inorganic substances provides energy to these types of organisms. They obtain energy from chemical reaction the chief inorganic electron donors are hydrogen sulphide ferrous iron etc the organisms which lives in deep veins of the sea are often categorised under chemoautotrophs some categories of chemoautotrophs are methanogens nitrifiers etc.

Note:
Heterotrophs are overall dependent on autotrophs for the substrate for the energy yielding products. Autotrophs are the ones which assimilate. Most common autotrophs are plants that convert light energy into chemical energy. They produce glucose molecules utilising carbon dioxide and water in the presence of sunlight.
