Why did fish survive in the lake but fish eating birds don't?

Answer 1

fish eating birds don't because there is no branch hangs above the lake . so no birds or bats hangging on the branch. so the bird eating fish cannot jump and eat the birds or bats.

Answer 2

Fish have adapted to survive in aquatic environments by developing gills to extract oxygen from water, while fish-eating birds rely on a different respiratory system that requires them to breathe air. If the lake becomes depleted of oxygen or contaminated with toxins, the fish may still be able to survive using their gills, while the birds would not be able to find suitable prey or may become poisoned by ingesting contaminated fish.
