Question

How many types of basic organic decomposition occur in Biomass energy conversion?

(a) 2

(b) 3

(c) 4

(d) 5

The question was posed to me during an internship interview.

Question is from Anaerobic Fermentation topic in chapter Biomass Energy of Energy Engineering

Answer 1

Correct answer is (a) 2

The best I can explain: There are two basic types of organic decomposition that can occur: aerobic decomposition (in the presence of oxygen) and anaerobic decomposition (In the absence of oxygen).  All organic material, both animal and vegetable can be broken down by these processes.
