Question

what are chemautotrophs..*

Answer 1

Answer:

Chemoautotrophs are the organisms that obtain energy from inorganic resources. They oxidise various inorganic substances such as nitrates, nitrites and ammonia and the energy which is released from the oxidation of these compounds, is used for ATP production. Such organisms can also extract chemical energy from reduced gases such as hydrogen sulphide, ammonia and methane. 

Some examples of chemoautotrophs are Nitrobacter, Nitrosomonas and Sulphur bacteria.

Answer 2

Answer:

Chemoautotrophs are organisms that obtain their energy from a chemical reaction (chemotrophs) but their source of carbon is the most oxidized form of carbon, carbon dioxide (CO2).
