They live in Arctic regions of Europe, Asia and North America.
To survive they live in burrows, usually in the side of a hill or cliff. Artic foxes do not hibernate and can withstand temperatures as low as -50 degrees C (-58 degrees F). A litter of 4 to 11 young is born in May or June after a gestation of 51 to 57 days. They are cared for by both parents.
Caribou eat mostly lichen and grass in the summer.
They live in Northern Europe ,Asia ,Scandinavia Siberia, Alaska, Canada, Greenland.
To survive they migrate hundreds of miles on the tundra and winter feeding grounds farther south to find grass and other tundra plants. Their main food in summer, but in winter caribou feed mainly on lichens, scraping away the snow with their hoofs to expose the plants.
Polar bears eat mostly Large and small mammals, fish, birds, berries,and leaves.
They live in coasts and ice floes in the Artic Ocean to southern limits of ice.
To survive the the polar bears are huge bears with an unmistakable creamy-white coat, the polar bear is surprisingly fast and can easily outrun a caribou over a short distance. It wanders over a larger area than any other bear and, of course, swims well.
They live in the tundra and grassland in Scandinavia.
To survive Norway lemmings are boldly patterned and are active day and night, alternating periods of activity with short spells of rest. Grasses, shrubs and particularly mosses make up its diet; in winter it clears runways under the snow on the ground surface in its search for food. These lemmings start to breed in spring, under the snow, and may produce as many as eight litters of 6 young each throughout the summer.
Lichens are on every continent, including both the Arctic and Antarctic.
They survive in all climates and altitudes. Some lichens have their certain requirements, but in general they need three things, undisturbed surfaces, time, and clean air.
Finding a lichen growing on your tree is a good thing.
Cushion plants grow in a low, tight clump and look like a little cushion. Cushion plants are more common in the tundra where their growth habit helps protect them from the cold.
They survive by their slow growing and adaptability when there is little to no water available.
Saxifrage grows in the northwestern U.S., the Arctic and, Antartica.
They need soil, water and sunlight.
They survive by The their well developed underground root system forstoring carbohydrates, so that they can respond quickly to the cold weather of the tundra.
The tundra is open planes with in some cases caverns, and ice fields. There is the odd glacier and old lake beds as well as actual lakes (mostly frozen).
Most vegetation in the tundra are low growing prennials that reproduce without seeds. Often they grow in crevices or rocks.
