How does the density of ice affect the survival of water dwelling organisms in environments where temperatures?
Some animals live both on land and in the water, and if the ice is too thick, they can’t get out. If it’s too thin, they can fall through the ice and into the water. This is what happens with the young of polar bears and harp seals- if the ice is too thin, the babies fall through, and since they don’t know how to swim and their blubber isn’t thick enough, they die. I don’t really know about animals that live exclusively in the water, though. Maybe it has something to do with the sunlight in the water creating algae which is food for a lot of small animals, which in turn are food for larger animals.
