Which term describes energy sources derived from ancient plant and animal matter?

• A. Solar energy
• B. Biomass
• C. Fossil fuel
• D. Geothermal

Answer: (C)

Fossil fuels are energy sources formed from ancient plant and animal matter that were buried long ago and transformed by heat and pressure over millions of years. This makes them coal, oil, and natural gas—derived from organisms that lived in the distant past. Solar energy comes from the sun, biomass uses recently living material, and geothermal energy comes from heat inside the Earth.
