प्रश्न
Explain how, sun is considered to be the ultimate source of fossil fuels
उत्तर
We know that green plants use sunlight for photosynthesis, which is the process by which they produce food for their growth. When animals eat plants for energy, they consume food made with the help of sunlight. When plants and animals die, their remains, which consist of material directly or indirectly made with the help of sunlight, are buried in the earth and converted into fossil fuels, such as coal and petroleum. Hence, the sun is the ultimate source of fossil fuels.
