Question

1. identify how temperature is a limiting factor for polar bears.

Explanation:

Polar bears are adapted to cold - Arctic temperatures. Warmer temperatures can melt sea ice, which is their primary habitat for hunting seals (main food source), resting, and breeding. Also, extreme heat can cause heat - stress in polar bears as they have thick fur and a layer of blubber for cold conditions.

Answer:

Warmer temperatures melt sea ice (habitat and hunting ground), and can cause heat - stress due to their cold - adapted physiology.
