For the same reason that it is important for any living things to have them. They may help a species survive environmental threatening environmental changes. Adaptations usually don't happen quickly, and the more advanced a species usually the narrower the range of adaptations that a species has. If another event similar to the one that ended the dinosaurs happened today, humans (for all of our intelligence and technology) would almost certainly die out. Insects and very small animals would likely make it through, as they have done before.
It is unlikely although not impossible that polar bears will be able adapt to the rapid changes affecting their habitat. Possibly within the lifetimes of some people now living, polar bears will be completely gone from the wild, and will live only in zoos.
Hollow, insulating fur and webbed feet are two functional adaptations of Polar bears.
Thick fur to keep it warm and white fur to help it camouflage with the snow.
why does the polar bear helps the polar ice
*Humans *Their prey
they are both polarised
Yes. Animals like the polar bear gave adaptations to help them survive in those conditions.
nothing it proobaly would die
A Polar Bear benefits from its adaptations because:1. It is always warm while it is in below freezing conditions2. It has good camouflage, especially when it is hiding.That is the best I can do
it keeps them warm
It helps the polar bear to stay hidden from predators as its paw is white. It may also help in camouflaging the polar bear as it catches prey. When the polar bear covers its brown nose, it looks exactly like the snow and ice surrounding it.
their white fur help them blend in with the snow polar bears fur insn't really white each piece is a clear hollow tube that keeps heat from escaping the polar bear
It allows them to keep their paws warm and allow them to keep from clipping on the ice by creating friction.
