Which of the following is the ultimate source of energy for us?

The Sun is the ultimate source of energy for all living organisms on Earth.

The Sun is an infinite and renewable source of energy, as well as our primary source of energy.

The sun's energy is essential for many processes, including photosynthesis, the water cycle, nuclear energy, cloud formation, the formation of fossil fuels, and so on.

All of our fossil fuels come from plants that lived millions of years ago.

There are several resources for storing the sun's radiant energy.

Plants are the most popular and widely used resource.

Plants use the sun's radiant energy to produce food, which they then store as chemical energy in their fruits, stems, and roots.
