Where does the energy stored in fossil fuel come from?

Answer 1

It comes from sunlight originally, since plants formed the original organic molecules.

When dead plants and animals were buried, compressed, and heated, their products (coal, oil, gas) retained the chemical energy stored in their molecules millions of years earlier.

Answer 2

This is what i think based on logic, but I'm not sure:Fossil Fuels used to be dead organic matter (plants/animals)The plants conducted photosynthesis and produced chemical energy which was stored inside them (in carbohydrates)Animals had access to chemical energy when they ate the plants --> energy flowed from plant to animal.When both plants/animals (with stored chemical energy) die, usually, decomposers turn them into nutrients etc, AND RELEASE ANY STORED ENERGY BACK TO ENVIRONMENT. However the plants/animals that form fossil fuels, can't be decomposed properly, since there isn't enough oxygen in the particular environment. Since they plant/animal is only partially decomposed, decomposers can't release energy back to environment, meaning stored chemical energy still resides in dead organisms. These organisms turn into fossil fuels over millions of years under heat+pressure, WHILE STILL CONTAINING THAT STORED CHEMICAL ENERGY.

And THAT'S WHERE CHEMICAL ENERGY IN FOSSIL FUELS COMES FROM!!! i think...

Answer 3

decayed organisms. after several years, the soil will push them into the rocky part of the earth near the core. of course, the core is very hot so those decayed organisms will be burned and will become oil.

Answer 4

The energy stored in fossil fuels comes from the sun. Millions of years ago, plants and organic matter absorbed sunlight through photosynthesis and converted it into chemical energy, which was then trapped in the fossil fuels through a process of decomposition and pressure underground.

Answer 5

Fossil fuels are nonrenewable resources that were produced millions of years ago by animals and plants. They are usually found underground.
