Answer 1

There is no denying the fact that the sun is the ultimate source of energy on planet earth. It is clear from the explanation provided below:

1. Plants make life on earth possible and the food prepared by the plants is undoubtedly a blessing of solar energy.
2. Plants convert solar energy into chemical energy via photosynthesis and prepare their food.
3. From pure coherent logic, the mechanical energy in our body by virtue of which we can do work is a blessing of solar energy. The food we eat is there for us predominantly when the plants convert solar energy into food.
4. Water is an elixir of life and the same water is available on the surface of the earth via the water cycle which is not possible without solar energy.
5. Production of hydroelectricity requires water that exists on the surface of the earth via the water cycle and the water cycle itself is possible only because of solar energy.
6. Solar energy is used by our body for producing various vitamins which help in various metabolic activities.
7. Solar energy is used in artificial satellites which make communication possible.
8. Solar energy is converted into electric energy by solar cells and has immense uses.

Hence, the sun is the ultimate source of energy.
