Which term describes energy produced by burning organic material such as plants and trees?

• A. Hydropower
• B. Solar Energy
• C. Biomass
• D. Oil

Answer: (C)

Biomass energy comes from burning organic material such as plants and trees. When you burn wood, crop residues, or other plant matter, the chemical energy stored in that material is released as heat, which can heat spaces or be converted to electricity. It’s considered renewable if the biomass is sourced sustainably because new plants can regrow and replace what was burned. In ideal conditions, the CO2 released is balanced by the CO2 the plants absorbed during growth, though actual emissions depend on combustion efficiency and processing. Other options describe different energy sources: hydropower uses moving water, solar energy comes from sunlight, and oil is a fossil fuel formed from ancient organisms rather than current plant material.
