I checked out the new Nootan even there nothings written about chemotrophs . On google it says its a type of sea organism . The maximum link i could get was that these organisms are important as they are the source of the heat-resistant enzyme Taq DNA
PolymeraseTaq
polymer,
one of the most important enzymes in molecular
biology
because of its use in the polymerase
chain reactionPolymerase chain reaction

In
molecular biology, the polymerase chain reaction is a technique to
amplify a single or few copies of a piece of DNA across several orders
of magnitude, generating thousands to millions of copies of a particular
DNA sequence...

(PCR) DNA amplification technique.

chemotrophs are org. tht gain energy by oxidation of electron donating molecules in the environment.......2 types.....1)autotroph...2)heterotroph...... ...thts all u need............. Wink

thanks man..!! is this important..?? i dont recollect my teacher teachng me this..!

chemotrophs are organisms that derive energy by oxidation
of inorganic compounds & use it for life processes.
eg:
->Sulphur bacteria (oxidise of sulphur compounds)
->Iron bacteria (oxidise of ferrous compounds)
->Hydrogen bacteria (oxidise of hydrogen to water)
->Nitrifying bacteria (oxidise of ammonia to nitrates)
