[@PRINCEKUMARCHAUDHARY.]

17:25
This statement is not entirely accurate. Fish do not photosynthesize; instead, they rely on dissolved oxygen in the water to breathe. When a layer of ice forms on a lake or sea, it can limit the exchange of oxygen between the water and the atmosphere, which can potentially lead to oxygen depletion and harm fish. However, the primary reason for fish die-offs due to ice accumulation is not their inability to photosynthesize but rather the reduced oxygen levels in the water caused by the ice cover blocking the exchange of gases with the air.
