Question

The Sun is the sole source of energy for all life on Earth.

• A. True
• B. False

Answer 1

The correct option is B False

The Sun is a predominant energy source for most life forms on Earth. However, there are several organisms living at the bottom of the ocean which can derive the energy that they need, from different substances and sustain their life processes. Some single-celled organisms also fall under this category where they do not require solar energy for their sustenance. There are also some viruses that are self-sustaining and meet their energy requirements by invading other organisms. Therefore, it can be inferred that the Sun is not necessarily the ultimate source of energy for all life forms on Earth.
