Question

The schematic diagram given here shows a food chain. Which one does not show the direction of energy flow?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

Energy flow is always unidirectional meaning going in one direction in food chain.

The 4th arrow doesn't show the flow of energy as it shows arrow both forward and backward direction.

Rest all arrows 1,2,3 shows flow of energy from plants to herbivore to carnivores and to decomposers respectively.

So, the correct answer is option D.
