  1. THE TUNDRA BIOME ByBas Dixon-Smith Year 6B

  2. THE BIOME: Tundra (Climate / geography)

  3. http://en.wikipedia.org/wiki/Permafrost • What is tundra climate/geography • The tundra is a barren , cold environment that has permafrost as one of its features • They are situated near the north and south poles • Permafrost is soil or rock that has been frozen for 2 or more years • There are no trees in tundra biomes • Ground that has permafrost in it is cracked because of the ice

  4. http://en.wikipedia.org/wiki/Permafrost Removal of ice-rich permafrost requires a jackhammer, as seen here. The image shows that the ice is trapped deep inside the soil strata, making it hard.

  5. http://en.wikipedia.org/wiki/Permafrost Permafrost can be a hazard when temperatures change; the ice expands; and the soil crackswith it. Here, you can see cracked soil falling into an adjacent pool of water.

  6. CHOSEN ANIMAL: The human

  7. Yes, humans live in tundra biomes. There are 3 groups of humans living in tundras all over the world: Inuit-Canada and Greenland Innu-Canada-Labrador and Quebec Yakut-Siberia-Russia

  8. ANIMAL ADAPTATION: to the Tundra

  9. Humans have adapted to the tundra biome by • Wearing clothes made out of caribou skins and fur to keep warm • Building igloos and discovering that they keep you warm • Towns incorporating above-ground water supply and other pipes to avoid freezing • Hunting local caribou, seals, whales and fish to eat: this diet is high in calories which increases metabolic rate and produces heat • Riding on sledges and dog sleds for transport

  10. THE CHOSEN PLANT and ORGANISM: moss and lichen

  11. Moss is a primitive, flowerless plant without ‘true’ roots

  12. Lichen is a simple organism made up of two parts a fungus and an algae • They combine to form a lichen • Lichens can grow on basically any surface that is well-lit • They can makechlorophyll which can make food. Each has something the other needs. This is called a symbiotic relationship.

  13. PLANT ADAPTATION: to the Tundra

  14. Moss can grow across the Tundra because it can survive in very wet conditions with little soil

  15. Lichen have adapted to the tundra biome by • Lichen can make food when the temperature is very cold and there is low light. • The tissues of lichens are resilient to frost. This makes it a great plant for the tundra. • Lichen can survive a long time without water by going into a dormant state.
