The Polar Bear Debate

A

Ring seals prey on polar bears, so as their numbers increase the polar bears decrease.

B

Walruses prey on ring seals, so as they increase in number ring seals also increase.

C

Polar bears don’t interact with these animals, so there is no connection to be made with this data.

D

Polar bears prey on seals and walruses, so as their population increases, the ring seals and walruses will decrease.
