Question

adapted features of polar bear

Answer 1

$\huge{\underline{\underline{\bf{\orange{Answer:}}}}}$

Polar bear :-

• The polar bear is a warm blooded animal. It can maintain its body temperature even in severe cold climatic conditions due to a thick layer of blubber. The blubber acts as an insulator. The thick white fur of polar bear also helps to keep its body warm. The fur also helps it to camouflage as it blends with the snow.
• It is a strong swimmer. It has wide and large paws that help in swimming and walking on snow.
• While swimming underwater, the polar bear can close its nostrils for a long duration of time. This allows it to swim under water for an extended period of time.

Answer 2

Answer:

Adaptations for cold climates

The Arctic is cold and windy with very little rainfall. Plants in the Arctic often grow very close to the ground and have small leaves. This helps to conserve water and to avoid damage by the wind.

The polar bear

Polar bears are well adapted for survival in the Arctic. Their adaptations include:

a white appearance - as camouflage from prey on the snow and ice

thick layers of fat and fur - for insulation against the cold

a small surface area to volume ratio - to minimise heat loss

a greasy coat that sheds water after swimming - to help reduce heat loss

large feet - to distribute their load and increase grip on the ice
