What are tge three fossil fuels that contain carbon from bodies of plants and animals that died millions of years ago?

The three fossil fuels that contain carbon from ancient plants and animals are coal, oil, and natural gas. Coal is primarily formed from plant material that accumulated in swampy environments, while oil and natural gas originate from the remains of marine organisms buried under sediment. Over millions of years, heat and pressure transformed these organic materials into the fossil fuels we use today.
