Answer 1

Answer:

1.→A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work. ... Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy.

2.→A fossil fuel is a hydrocarbon-containing material formed underground from the remains of dead plants and animals that humans extract and burn to release energy for use. The main fossil fuels are coal, petroleum and natural gas, which humans extract through mining and drilling.
