Question

The burning of coal, a fossil fuel, produces water and carbon dioxide. How is this similar to cellular respiration?

Answer 1

Carbon dioxide and water are bi-products of both cellular respiration and the burning of fossil fuels. 

Answer 2

Both release carbon into the atmosphere, but burning fossil fuels releases CO2 at a much greater amount.

Both cellular respiration and combustion require a core fuel for the process to happen at all.
