If all the vegetation in the pond died what effect would it have on the animals
KiRa [710]

If all the vegetation on a pond died then the organisms and fishes that lives on that pond will no longer have anything to eat and anything to live, thus the probability is that they will also die. Let’s put ourselves in the shoes of those fishes. If all the plants and vegetation died on that pond, it’s like our home and food were taken from us. Then there’s nothing left.
