I don't have Polar bears...
I have Polar bears because I think that they are more cuddly than Pandas OR Koalas.
first the question doesnt make sense,polar bears r here because they just live on earth
They generally don't have to hide as most of the time they are the top predator in their niche but when they do hide, it is normally to avoid a confrontation with another predator or to stalk prey.
Bears are a keystone species: They thin out the herds of deer, elk, or caribou as well as spread undigested seeds (and fertilizer) far and wide.
yes
No. There are no bears that exist in the continent of Africa, which is where leopards reside.
No. Horses do not exist where polar bears live.
Panda bears are necessary for humans to exist.
In a person's imagination, anything may exist.

Not living ones that walk and breathe, but the ones you can eat DO exist! ^_^

Koalas do exist. Koala bears don't. Someone has picked up this term but it is incorrect. Koalas are definitely not bears, but marsupials unique to Australia.
