The Ultimate Source of our Energy is (A) Sun (B) Plants, (C) Electricity, (D) Wind

Answer: A ‘Sun’.

Explanation: The Sun is an unlimited and renewable supply of energy and our primary source of energy.

The sun’s energy is essential for numerous activities, including photosynthesis, the water cycle, nuclear power, cloud formation, the creation of fossil fuels, and so on. It gives organisms the light they need for growth, everyday routines, daily regularity, etc.

Plants use water and carbon dioxide to transform the sun’s radiative energy into chemical energy (carbohydrates), which they keep in their leaves, stem and roots. This type of energy stored is also referred to as biomass energy. Biomass is a renewable source of energy.
