Answer:
Polar Bears feed on seals. So, polar bears and seals share a prey predator relationship. If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
