How has the Polar Bear adapted to survive in the Artic Tundra?
Details on the specific location
The artic tundra biome can be found in greenland, alaska, nothern russia, and northern canada - anywhere near the north pole.
The artic tundra is also found in the artic coast of north america.
Longitude and Latitude
The Latitude and Longitude for the Artic Tundra is 71.2 degrees North and 156 degrees west. The artic tundra is cold and windy and is close to the north pole.
Climate
Precipitation in the artic tundra is generally dry snow and in the summer cyclonic storms form on the boundary between open ocean and sea ice.
Even though the warmest month's temperature doesn't rise above 10 degrees, the days are lengthy. In the warmer months, the snow cover melts.
Winters in the artic tundra are long, cold, and can be below 0 degrees celsius for 6-10 months.
Polar Bear
Adaptations
Structural Adaptation
Polar bears have strong jaws and teeth which is good for hunting and eating other prey.
Polar bears have a good sense of smell. They can pick up the scent of a prey from over a kilometer away, which is good for hunting and locating food in an environment with seldom amount of animals.
Behavioural Adaptations
The polar bears go into a walking hibernation-like state when food is scarce. That lowers their body temperature, heart rate, and breathing rate.
They have a high fat diet to keep warm, which is why seals are an important part of their diet.
Physical Adaptation
Polar bears have 2 layers of thick fur that prevent all heat lost to the point that when an adult polar bear runs they can quickly overheat.
Polar bears have paws as big as dinner plates that help them navigate the harsh and cold terrain. The paws measure up to 30 cm which prevents them from falling through when they walk on thin ice. The polar bear's paws are also designed for swimming as they act as paddles and rudders.
Polar bears have thick, curved, sharp, and strong paws which is good for catching and hold slippery seals and gain traction on ice.
Information
Polar bears are the apex predators of the artic tundra. They are in the bear family and they feed on seals. They are also mammals since the mother bear gives birth to cubs and the cubs rely on milk from the mother bear.
Overview of the Artic Tundra
Polar bears, snowy owls, and artic foxes are the apex predators of the tundra. The secondary consumers are seals which feed on fish and get hunted by polar bears. The primary consumers are fish who feed on algae which is a producer. The decomposers in the artic region are bacteria and fungi.
