Tundra
By Stefan Russell
Climate of a Tundra
The average winter temperature is -34° C (-30° F), but the average summer temperature is 3-12° C (37-54° F). Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). Seasons do change in a tundra but not much changes, it is still very cold and small plants begin to grow back in the summertime.
Polar Bear
A Polar Bear is an animal that lives in tundras around the world.
Tundra and its Location.
This is a picture of a Tundra and some of the plants that live in a tundra. Tundras are located at the top of the world, around and at the North pole.
Tundra Animals and Plants
This is a picture of some of the animals and plants that live in a Tundra.
Abiotic Factors
This is a picture of the average amount of rainfall per year in a tundra. The highest tempature recorded in a tundra in Alaska was 5 degrees Celcius. The most rainfall was about 25mm. In a month.
Plant Life
The plants adapt by growing short and close to the ground to avoid high winds. Hairy stems also keep plants warm in the tundra. The Tundra has little plant life within this biome. Some common plants include the Bearberry, Arctic Moss, Caribou Moss, Diamond Leaf Willow, and Labrador Tea. This plant also has a hairy stem to keep warm. No animal eats the Labrador Tea. Just like the rest of the plants it has a hairy stem and stays close to the ground to keep as warm as possible. Animals and people eat this willow because it has a lot of vitamin C, vitamin A, and Calcium. This plant is not as populated as the others because so many people and animals eat this.
Animals
Animals that live in the tundra have special adaptations that allow them to survive the
extreme temperatures and conditions that are in a tundra. The Arctic Fox has short ears
and a short, round body with a thick coat to protect it from the freezing temperatures.
Bunny
The bunny has a think coat of white fur to blend in with the snow so it cannot be easily seen by its preditors and to stay warm.
Snow Fox
The snow fox has white fur to blend in with the snow so it can sneak up on prey easily without being seen.
Polar Bear
The Polar Bear has a thick coat of fur to stay warm during the freezing winter nights and the cold wind. They also have white fur to blend in with the snow.
Snowy Owl
The snowy owl has white feathers to blend in with the snow so it can sneak up on prey without being seen.
Bison
The bison have a thick coat of fur to protect itself from the cold wind and snow.
2 Examples of Cooperation and Competition
Cooperation- The small spikes on the stems of plants help protect it from getting eaten by much bigger animals. Another one is when elk stay in packs they are not hunted because one lone wolf cannot take on all of them.

Threats to Tundras and Endangered Species
Two endangered species located in tundras are Polar Bears and Arctic Fox.
The global importance to this biome is very important, because with out this biome many food webs and chains would be interrupted and disturbed.
