Here's why polar bears can't survive in the desert:
* Lack of Food: Polar bears rely on seals as their primary food source. These seals live in and around the sea ice, which is essential for polar bear hunting. Deserts lack any equivalent to this ecosystem.
* Extreme Heat: Polar bears have thick layers of blubber and fur to keep them warm in the Arctic. This insulation would make them overheat in the desert's extreme temperatures.
* Lack of Water: Polar bears are adapted to get the water they need from the snow and ice they eat. Deserts have limited water sources, and polar bears wouldn't be able to survive without access to fresh water.
* Different Predators: The desert has different predators than the Arctic, such as lions, wolves, and snakes. Polar bears are not equipped to deal with these predators and would be vulnerable in this environment.
In short, polar bears are perfectly adapted to the Arctic and would quickly perish in the desert.
