Which is the renewable exhaustible natural energy resource?

Biomass

The correct answer is Option (4) –Biomass

The renewable exhaustible natural energy resource among the options provided is: Biomass

Biomass refers to organic materials, such as plants, wood, agricultural residues, and animal waste, that can be used as a source of energy. It is considered renewable because it can be replenished relatively quickly through natural processes. Biomass energy can be obtained through various methods, including burning for heat or electricity generation, conversion into biofuels such as biodiesel and ethanol, and anaerobic digestion to produce biogas. Unlike fossil fuels like petroleum, kerosene, and coal, which are non-renewable and finite resources, biomass can be sustainably managed and harvested for ongoing energy production.
