Where did Fossils fuels originally get their energy from?

Answer 1

Nearly all energy on the earth comes originally from the sun - including fossil fuels. To the best of our knowledge, fossil fuels come from the conversion of deposits of matter that was once living into the fuel via lots of pressure, heat, and time after it was buried deep in the crust. The plants that contribute to the fossil fuels got their energy from the sun via photosynthesis. The animals got their energy ultimately from the sun by eating plants that got their energy from the sun by photosynthesis or other animals that ate the plants that got their energy from the sun by photosynthesis.

Answer 2

Fossil fuels, such as coal, oil, and natural gas, originated from plants and microorganisms that lived millions of years ago. These organisms absorbed energy from the sun through photosynthesis and stored it in their tissues. Over time, their remains were buried and underwent chemical changes, resulting in the creation of fossil fuels.

Answer 3

Digestion of other plants and animals
