Question

How can we create 5 Joule of energy for our use?

• A. By growing crops
• B. By eating food
• C. By sleeping
• D. By no means

Answer 1

The correct option is D By no means

Energy can neither be created nor it can be destroyed but it can be transferred from one source to the another, e.g., From the sun to plants/phytoplanktons and then to all other sources which are directly or indirectly dependent on the plants.
