Solution
The correct option is D Hydrolysis The organisms which derive its energy by the breakdown of organic matter are known as chemo organoheterotroph. They hydrolyze the complex organic compound like carbohydrates, lipids, and proteins by chemical reaction and converts them into simpler compounds which can be easily metabolized to form energy.
Hydroloysis is an exergonic reaction which involves the splitting of bonds due to additions of water. This is used by several heterotrophs to derive energy from complex molecules by splitting of bonds by addition of water.
Decomposers are a suitable example of chemo organoheterotroph.
