1. Tundra Biome research By Peyton Quillin

2. Tundra Geography & Climate Location: Arctic circle, Antarctica Description:Cold,Dry Soil type:frozen,permafrost Precipitation:25 cm per year Temperture:winter:-50,summer:50 Climate:snowy,cold

3. Tundra Biodiversity Plants: mosses, grasses, small shrubs, and lichens. Animals: ducks, geese, shore birds, hawks, snowy owls, willow grouse,mice,voles,lemmings. http://images.google.com/search?q=tundra+animals&tbm=isch&hl=en&gbv=2&gs_l=img.1.1.0l10.2073.9062.0.1161 0.11.6.1.4.4.0.83.306.6.6.0...0.0...1ac.1.dTazPRkE9UQ&surl=1&safe=active&oq=tundra animals

4. Tundra adaptations needed for survival Plants: the ability to survive the freezing cold and droughts Animals: Ptarmigan-Their feet are covered in feathers to keep from sinking in the snow. http://images.google.com/search?tbm=isch&hl=en&source=hp&q=ptarmigan+bird&gbv=2&oq=ptarmigan&gs_l=im g.1.1.0l10.2073.9062.0.11610.11.6.1.4.4.0.83.306.6.6.0...0.0...1ac.1.dTazPRkE9UQ&surl=1&safe=active

5. Tundra Interactions of Biotic and Abiotic Biotic: birds to tree: tree provides shelter for the birds. Also owls, and other birds Abiotic:rain: provides the little snow they get. Wind: carries the seeds the plants produce.

6. What is Biodiversity? Biodiversity-The number of plant and animal species in a area.

7. How does biodiversity contribute to the sustainability of an ecosystem? The predators need variety to survive. If one species dies and that is the predators only meal than the predators die off. The prey will grow in size and run out of food and die off too.
