  1. Tundra BY:BADER-AL-ALSHAMLAN

  2. INTODUCTION Tundra is one of the coldest of all biomes. It is also big, The tundra covers one fifths of the earth. The word tundra comes from Finland it mean’s treeless plain. Tundra are located in the Arctic circle.

  3. Abiotic Factors Average annual temperatures are -70°F (-56°C). it doesn’t affect the animals much because they all are adapted with thick fur , short ear etc. plants are also not affected much because the plant are very short in height and their roots are very short. When the temperature is reaching around 10 degrees , the small plants start to grow faster and develops flowers and seeds.

  4. POLAR BEAR The skin of the polar bear is black so it can retain the heat in it’s body, and It can prevent heat loss from it ears because they have short ears.

  5. CARIBOU Caribou has thick fur and skin to help them to enter frigid rivers during the time of migration in the tundra region.

  6. Artic Fox Artic fox has thick fur on its feet and over the body to keep warm always , it has small ears, small body and a bushy tail that curls around it’s body.

  7. Arctic Hare The Artic hare has thick fur. In the summer the white coat will change into a blue, grey or brown coat. They have big hind feet and claws so they move around faster and dig faster.

  8. Snowy Owl They have thick layer of feathers around their body. They can rotate their head 270 degrees

  9. Plants There is barely any vegetation in the tundra. The plants present in this region are shrubs, grasses, lichens, mosses etc. The layer of snow acts as a protective layer for these during cold winter months.

  10. Human Activities Tundra region are not affected much by the human activities because its not easy to reach and stay there. But now tundra region is also started to face the impacts of human activities like oil exploration and tourism. I believe that the human activities are bad because the plants and animals live there are going to get instinct. We need to control the tourists from going there and also ban the oil exploration.
