  1. Arctic Biome By Ben Keller, Dan Romanelli

  2. Biotic Polar Bear Arctic Fox Arctic Seal Walrus Abiotic Ice Snow Water Average temp. 10 degrees F Low precipitation rate- 28 in annually Features

  3. Limiting Factors • Subzero Temperature • Ice melts in summer • Little plant growth

  4. Trophic Levels Arctic trophic levels are very inefficient. 95% of energy is lost at each level. Most of that energy is needed by the organism to maintain body heat.

  5. Food Web

  6. Polar Bears • Polar Bears are specialized predators of seals. • They have thick fur and a layer of blubber to keep them warm and webbed feet to help them swim. • Their only competition is other polar bears

  7. Arctic Fox • The Arctic Fox hunts small prey • To keep warm they have thick fur and high amount of body fat. • Their fur changes color seasonally • They compete for food with polar bears

  8. Grows on exposed rock and inside crevices Fuzzy covering protects them from wind Purple Saxifrage

  9. Although it’s called moss it is actually lichen It can survive long periods without water by going dormant Caribou and reindeer like to eat it Caribou Moss

  10. Symbiotic Relationships • Caribou moss is a lichen which is fungus and algae living in a mutual relationship. • mycorrhizal fungi live on plant roots and decompose nutrients for the plant. • Parasites, like fleas and ticks, live on caribou and other arctic animals and suck their blood.

  11. Cycles of the Arctic • There is little decomposition in the arctic making the soil build up with carbon and nitrogen. • Due to the cold temperature there is little evaporation causing little rainfall.

  12. Succession Because of rising temperature in the arctic more plants are growing further north than before

  13. Environmental Issues • Due to climate change arctic ice is melting more and more each year. • Mining and drilling are spreading further north • Changes to the arctic environment can have major consequences

  14. Help Save These Gentle Giants

  15. The Arctic Council The Arctic Council is an intergovernmental organization dedicated to environmental protection of the arctic and cooperation of arctic states. Countries part of the Arctic Council are: Norway, Sweden, Finland, Iceland, Denmark, Russia, Canada, U.S.
