(N/A) Fossil fuels are the remains of plants and animals that were buried deep underground millions of years ago.
$1$. Plants capture solar energy through the process of photosynthesis and convert it into chemical energy stored in their tissues.
$2$. Animals obtain this energy by consuming plants or other animals that have consumed plants.
$3$. When these organisms died and were buried under high pressure and temperature over millions of years,their remains were converted into fossil fuels like coal,petroleum,and natural gas.
Therefore,the chemical energy stored in fossil fuels is essentially the solar energy that was trapped by plants long ago.
