Answer 1

Question:

Describe the natural vegetation and wildlife of the Tundra region.

Answer:

Beyond the Arctic and Antarctic Circles is the region of Tundra vegetation. Here the winters are long and cold, and the growth of all vegetation is confined to a very short, cool summer. The wildlife in the icebound Antarctic region is confined to the coast only. Natural vegetation and wildlife in the region includes:

1. dwarf willows in sheltered hollows and valleys, mosses and lichens
2. cranberry bushes and arctic flower plants that bloom in summer
3. reindeer, polar bears, musk oxen, arctic hares, foxes, penguins, walruses, seals, etc.
4. duck, geese, snow buntings and other birds.

Birds migrate to warmer regions in winter. Some animals like reindeer also migrate.

Answer 2

Dwarf shrubs, sedges and grasses, mosses, and lichens make up the tundra's plant life.

• Some tundra environments support sporadic tree growth. The term "tree line" or "timberline" refers to the ecotone (or ecological boundary zone) that separates the tundra from the forest.
• Nitrogen and phosphorus are abundant in the tundra's soil. The musk ox, the Arctic hare, the polar bear, the Arctic fox, the caribou, and the snowy owl are among the creatures that inhabit the tundra.
• Caribou and semipalmated plover are two examples of creatures that inhabit the tundra and move to warmer climes in the winter.
• Winters in tundra areas are bitterly cold and snowy. Summers are pleasant. Although in maritime regions the limiting summer temperature can be lower, the southern or lower limit of trees typically corresponds to a mean July temperature between 10 and 12 degrees Celsius (50 and 53.6 degrees Fahrenheit).
• In the vicinity of treeline, low shrubs that are less than one metre (3.2 feet) tall and peaty soils are typical.
• The landscapes are primarily barren in the northernmost regions and at higher elevations, with sporadic mosses, lichens, and wildflowers like purple mountain saxifrage and Arctic poppies. Permafrost, a permanently frozen layer of earth that is buried beneath a thin layer of soil that thaws every year, lies beneath the majority of the Arctic tundra regions.

Hence the tundra region is mostly barren.
