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.
And THAT'S WHERE CHEMICAL ENERGY IN FOSSIL FUELS COMES FROM!!! i think...
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.
Fossil fuels are nonrenewable resources that were produced millions of years ago by animals and plants. They are usually found underground.
U don't know anything u can't help me
animals
The sun.
Potential
Fossil fuel. Also, natural gas is in the category of fossil fuels.
it is stored as something called prototype energy which is energy, a little more abundant than fossil fuels. +++ "prototype energy" doesn't exist. The energy stored in any fossil fuel, or in materials like wood, is potential chemical energy,
Fossil fuels represent chemical energy, a form of potential energy. This energy was stored in the hydrocarbon molecules and can be released by oxidation (burning).

combustion
Not fission. The sun's energy is produced by nuclear fusion, and that energy produced all the vegetation which turned into fossil fuel.

Burning the stored energy of fossil fuel

Fossil fuels contain the chemical energy that plants and algae obtained from sunlight and then stored in sugars. Just as energy chemical energy is stored in sugars, chemical energy is stored in fossil fuels. All it takes to release it is enough heat and oxygen to cause the fuel to burn.
