Question

Why did the fish in the second jar die even after providing water and food?

• A. Lack of sufficient food
• B. Lack of sufficient water
• C. Lack of sufficient oxygen
• D. None of these

Answer 1

The correct option is C

Lack of sufficient oxygen

The second jar has dissolved oxygen in its water but it gets exhausted after sometime because the fish breathes in the same water throughout. It becomes slow and fatigued and eventually dies due to scarcity of dissolved oxygen.
