Question

The glow worm produces light energy from:
(A) Potential energy
(B) Nuclear fusion
(C) Electrical energy
(D) Chemical energy

Answer 1

Hint:
For answering this question, we have to consider the basic process of energy generation in living organisms. Then considering the type of energy generated from the process will give an answer for this question.

Complete step by step answer:
A glow worm is one among various insect larvae that glow through the process of bioluminescence. Bioluminescence is a process of production and emission of light by living organisms. A chemical reaction occurs between an enzyme, ATP (Adenosine triphosphate) molecule, oxygen, and a waste product, which generates the required chemical energy which is emitted as light.
Hence, the correct answer is option (D); chemical energy.

Additional Information
The glow worms, like other insect larvae, glow through bioluminescence. It is the production of light by a living organism. In this process, the enzyme known as luciferase reacts with a waste product known as luciferin, adenosine triphosphate molecule, and oxygen to generate chemical energy. This chemical energy is emitted in the form of blue/green light.
This phenomenon helps these organisms to warn the predators that they are not worth attacking due to toxins present within them. It also helps them to attract other insects for their meal. Also, they use it for communicating between themselves.

Note:
All the processes corresponding to living organisms are governed by the chemical reactions that keep taking place inside them for their survival. So, the energy required for almost any kind of phenomenon shown by them is provided by the chemical energy which is generated by such chemical reactions.
