They live near the arctic circle because it is cold and they adapt very well to the cold environment. Polar bears need to live near the arctic circle because if they live in the desert, they will die because they will not adapt well to the weather.
Can a polar bear survive in a desert area give reason?
Polar bear can’t survive in the desert as they needs very cold temperature as they have a lot of hairs on their body…..
Can a bear live in the desert?
Brown bears can be found in many habitats, from the fringes of deserts to high mountain forests and ice fields. In Europe, the brown bear is mostly found in mountain woodlands, in Siberia it occurs primarily in forests while in North America they prefer tundra, alpine meadows and coastlines.
How do polar bears adapt to the desert?
The polar bear
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.
Why can’t polar bears live in hot places?
Polar bears will not be able to surmount the impacts of global warming on their Arctic habitat, according to scientists, because they will not be able to adjust their metabolism to survive on land-based prey during longer and longer periods with no sea ice. …
What would a polar bear need to survive in the desert?
Polar bears can survive in the most harshest tundras but do you know that it can’t survive in the desert because a polar bear is hardwired to have a lot of fur and it would probably die of dehydration. Anyway on to the facts a polar bear has very sharp claws so he can snag a fish or seal from the icy water.
What problems will a polar bear have if it is left in the desert?
Since the normal habitat of a polar bear is cold regions it would die of heat stroke in the desert and also polar bears have blubber for insulation and this would cause further heating of their bodies and eventual death.
Why do bears pop their jaws?
These sounds are rarely a sign of aggression, more often a signal that the bear is concerned, nervous or merely upset at what’s going on. If a bear is woofing at you, popping its jaws or moaning it is telling you it is upset or troubled and is communicating to you to move on.

All bear species except for one live in either temperate or tropical woodlands. Only the polar bear is a stranger to the forest, living and foraging instead across vast expanses of barren polar ice.
Why a polar bear would not survive in a grassland?
A new research has stated that polar bears face starvation as their frozen habitat shrinks because they will not adapt to land-based foods. … Polar bears have evolved to survive on the energy-rich, fatty flesh of seals. In the regions around the ice edges, they naturally spend the summer months on land.
Why do polar bears have 42 teeth?
Polar bears have 42 teeth, which they use for catching food and for aggressive behavior. Polar bears use their incisors to shear off pieces of blubber and flesh. Canine teeth grasp prey and tear tough hides.
How has polar bear adapted?
Polar bears live in one of the planet’s coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice.
How do polar bears adapt to climate change?
While polar bears have shown some ability to adapt to changes in their surroundings – for example, by foraging for food on land – scientists project polar bears will become more food-stressed as sea ice diminishes and populations will decline. … There are other impacts of climate change on polar bears, too.
