2. It is found in both poles of earth.
3. It has endangered status on the IUCN red list of endangered species.
Which of the statements given above is/are correct?
Polar bears live in the Arctic, but not Antarctica. Down south in Antarctica you’ll find penguins, seals, whales and all kinds of seabirds, but never polar bears.
- Polar bears are carnivores. In the summer, they may consume some vegetation but gain little nutrition from it. Their primary prey are ringed seals (Pusa hispida).
- They also hunt bearded seals (Erignathus barbatus), harp seals (Pagophilus groenlandicus), hooded seals (Cystophora cristata), walruses (Odobenus rosmarus), sea birds and their eggs, small mammals, fish and scavenge on carrion of seals, walruses, or whales.
- Bears often leave a kill after consuming only the blubber. The high caloric value of blubber relative to meat is important to bears for maintaining an insulating fat layer and storing energy for times when food is scarce.
- Polar bears do not store or cache unconsumed meat as other bears do.
- ‘vulnerable’ status on the IUCN Red List of endangered species
