Question

Quizplus · Accepted Answer

Fossil fuels are formed from the remains of ancient autotrophs (plants and algae) that have been buried under sediment and subjected to heat and pressure over millions of years. They cannot be recycled and are distinct from biofuels, which are derived from living organic matter. Fossil fuels also include coal, oil, and natural gas, and are not currently being generated by living autotrophs. They are not exclusively the remains of dinosaurs, as they also come from ancient marine organisms and other prehistoric organisms.
