What are chemoautotrophic prokaryotes, and where have they been -found to support whole communities?

Answer 1

Chemoautotrophic prokaryotes are those prokaryotic organisms which perform chemosynthesis or prepare food with the help of energy obtained from chemical reactions of inorganic substance present in their external environment, they are able to prepare food by themselves with the help of chemical reactions.

Chemoautotrophic prokaryotes are found in lava beds(iron-oxidizing bacteria), in soil(nitrogen-fixing bacteria), deep-sea thermal vents, etc. They support the whole community as they play a significant role in recycling nutrients like iron, sulphur, nitrogen.
