What is the only source of energy?

The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

Why do you think the source of energy is from outside?

Answer: The outside sources of energy is usually quite varied, since the environment is not under the control of the individual organism. Hence these energy sources need to be broken down or built up in the body, and finally converted to a uniform source of energy.
