Sea ice is critical to the polar bear because these bears hunt from this ice.

As the north warms in spring, the bears wait for the ice to begin to break up as they begin to venture out on it. There on the ice they will try to take seals, walrus, or anything else they might catch. Even the mothers take their cubs out on this ice as seals use it to den and can be hunted from the frozen platform.

Polar bears are beneficial to the Arctic ecosystem where they live in the same way as other apex predators. By hunting for food, they help to prevent the populations of their prey animals (primarily seals) from growing to a dangerous level. By keeping prey populations at a healthy level, they help to prevent their prey (seals) from overeating the animals below them (fish).
