UPSC NDA-1 – 2021
A) Wood is organic matter from trees and is a common biomass fuel.
C) Gobar gas (Biogas) is produced by the anaerobic decomposition of organic matter (like cow dung), making it a biomass energy source.
D) Coal is formed from ancient organic matter (plants) under heat and pressure over millions of years. While originated from biomass, it is classified as a fossil fuel and is distinct from renewable biomass sources used today.
B) A nuclear reactor generates energy through nuclear fission, typically using elements like uranium. This process involves the splitting of atomic nuclei and is not related to organic matter or biomass. Therefore, a nuclear reactor is not a biomass energy source.
