Biotic And Abiotic Factors On Tundra

Abiotic Factors-Physical, or nonliving, factors that shapes an ecosystem
 
  • Strong Winds
  • little precipitaion (rainfall)
  • short summer days
  • very long and cold winters
  • poor soil
  • permafrost-a layer of permanently frozen subsoil

Biotic Factors-biological influences on organisms within an ecosystem

  • Plants like Heaths and mosses have to adapt to the very long and cold winters because the sun does not come up in the winter
  • Wildlife like arctic tundra animals include snowy owls, reindeer, polar bears, white foxes, lemmings, arctic hares, wolverines, caribou, migrating birds, mosquitoes, and black flies.
