1. The Tundra

2. Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. Characteristics of tundra include: Characteristics of tundra include: Extremely cold climate Extremely cold climate Low biotic diversity Low biotic diversity Simple vegetation structure Simple vegetation structure Short season of growth and reproduction Short season of growth and reproduction Energy and nutrients in the form of dead organic materia Energy and nutrients in the form of dead organic materia Large population oscillations Large population oscillations

3. Arctic tundra Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga. The arctic is known for its cold, desert-like conditions Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga. The arctic is known for its cold, desert-like conditions The growing season ranges from 50 to 60 days. The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F) which enables this biome to sustain life The growing season ranges from 50 to 60 days.

4. Plant life on the tundra Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. The growing season is approximately 180 days. The nighttime temperature is usually below freezing Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. The growing season is approximately 180 days. The nighttime temperature is usually below freezing tussock grasses, dwarf trees, small-leafed shrubs, and heaths tussock grasses, dwarf trees, small-leafed shrubs, and heaths Plant life in the tundra is few, and the growth is low Plant life in the tundra is few, and the growth is low

5. Plants! The Tundra has a lot of plant life within this biome. Some common plants include the bearberry, arctic moss, Caribou moss, Diamond leaf willow, Labrador Tea The Tundra has a lot of plant life within this biome.

6. Animal life in the Tundra The Arctic Tundra is full of life!!! The Arctic Tundra is full of life!!! There are caribou, reindeer, birds, foxes, wolves, grizzly bears, polar bears, arctic hare, bison and much more! The owl, ptarmigan, geese and terns all migrate to the Arctic in the spring to nest. Herds of reindeer and caribou move south to migrate in the winter. There are also whales in the Arctic There are caribou, reindeer, birds, foxes, wolves, grizzly bears, polar bears, arctic hare, bison and much more!
