Unlike the vast majority of the deep-sea environment, polar seas are very nutrient rich and highly productive. But, like the deep-sea, they are also fiercely cold, imposing many of the same thermal challenges to the sharks and other creatures that live there.
What is it like to live in the polar climate?
Polar climates are almost always covered with snow and have extremely cold temperatures. The temperature rarely rises above the freezing point and it often sits far below zero, way colder than the winters you might be used to!
What is the polar ecosystem like?
polar ecosystem, complex of living organisms in polar regions such as polar barrens and tundra. Polar barrens and tundra are found at high latitudes on land surfaces not covered by perpetual ice and snow. These areas lying beyond the tree line comprise more than 10 percent of the Earth’s land surface.
What is it like living in the Arctic?

What is the polar climate like for kids?
What’s a polar climate like? A polar climate is dry, with some areas experiencing less than 250mm of precipitation a year. This is why, for example, Antarctica is considered a ‘cold desert’. Temperatures here are always very low.
Which of the following animals survive in polar habitat?
Polar bears and arctic foxes are adapted to the extreme weather of the Arctic region. Walruses and humpback whales live in the Arctic ocean. Several kinds of penguins, including the emperor penguin, live in Antarctica, and so do walruses and narwhals. The poles of the planet are places of extremes.
Why is the polar ecosystem important?
Arctic marine ecosystems are important constituents of global biodiversity. … The marine Arctic also provides habitat for large populations of marine mammals and birds (see Reid et al., Chapter 3 and Ganter & Gaston, Chapter 4), some of which form colonies that are among the largest seabird colonies on the planet.
What is the climate like in polar regions?
A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice.
What lives in the Arctic Ocean?
Species like the beluga, pacific salmon, brown bear, walrus, arctic wolf, arctic fox, narwhal, and gray whale live here. Polar bears remain the most iconic Arctic species, and live only in this landscape.
How long can you survive in Arctic water?
Generally, a person can survive in 41-degree F (5-degree C) water for 10, 15 or 20 minutes before the muscles get weak, you lose coordination and strength, which happens because the blood moves away from the extremities and toward the center, or core, of the body.
Where do people live in the polar region?

Do people live in North Pole?
No one actually lives at the North Pole. Inuit people, who live in the nearby Arctic regions of Canada, Greenland, and Russia, have never made homes at the North Pole. The ice is constantly moving, making it nearly impossible to establish a permanent community.
