Energy fuels cellular activities.
I believe they are biotic. Biotic means that it is living or once was living. Abiotic means never alive. Fossil fuels are compressed plants, and plants are living things.
Biofuels are fuels made from living things, while fossil fuels are made from the decompostion of plants and animals that have died.
Fossil fuels are biotic, as they are formed from the remains of once-living organisms that were buried and subjected to high pressure and heat over millions of years. This includes fuels like coal, oil, and natural gas.
fossil fuels are called 'fossil' fuels because they started off as living things, in the same way as the fossils you see in mueseums started off as living things fossil fuels include coal, crude oil, natural gas and peat
Carbon and hydrogen mainly, there are also undesirable smaller quantities of sulfur
biofuels make energy from living things or their waste products
This element is carbon.
