Question

Which one of the following is not a bio-mass energy source?
1. Wood
2. Nuclear reactor
3. Gobar gas
4. Coal

Answer 1

Correct Answer - Option 2 : Nuclear reactor

CONCEPT:

Bio-mass energy:

• Bio-mass is the energy source that is received from animal wastes and plant materials.
  • For example, cow-dung, various plant materials like the residue after harvesting the crops, vegetable waste, and sewage are decomposed in the absence of oxygen to give biogas.

EXPLANATION:

• From the above, it is clear that wood, gobar- gas, and cow-dung are an example of a biomass energy source. Therefore option 1, 2, and 4 is not a bio-mass energy source.
• On the other hand, nuclear energy is obtained from nuclear fusion and fission. Therefore option 2 is the answer.
