  42. 42. 43Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of the boreal forest?Abiotic features:•Long, cold winter season•Warm summers•Moderate rainfall•Much of the precipitation is snow•Snow insulates and protects groundspecies
  43. 43. 44Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of the boreal forest?Biotic features:•Few species•Mainly black spruce forest and bogs•Black bears, red squirrels, and moose•Many biting flies•Reduced ecosystem productivity dueto short growing season

  45. 45. 46Ecosystem Review – DO NOT COPYWhat are the abiotic and bioticfeatures of a beaver pond?Abiotic features:•Shallow water•Warm water in summer, ice-covered in winter•Temporary, but lasting years todecades•May break, causing floodingdownsteam
  46. 46. 47What are the abiotic and bioticfeatures of a beaver pond?Biotic features:•Community ofplants, fish, frogs, turtles, insects,and beavers•Surrounding forest is a foodsupply for the beavers•Flooding kills trees, which arethen used by species as food orshelter.Ecosystem Review – DO NOT COPY
