Questions

The energy in petrol originally came from the sun. Explain how it got into petrol. 

We know that green plants use the energy from sunlight for photosynthesis and growth. They store this energy in the form of carbon compounds. Thus, every leaf and every bit of wood in plants and trees is made using the energy from sunlight. Animals eat plants for energy, which is originally received from sunlight. These plants and animals die and their remains get converted into coal and petrol, respectively, which are energy-rich compounds of carbon that were made by plants using solar energy.
