    Air, homes, carbon cycle, food, soil.
  33.                  If the number of snakes in this food web decreases, what will happen to rabbits and hawks at first.
    Hawks will decrease rabbits will increase
  34.                  If the pine trees are the main habitat for the birds, what will most likely happen to their population if a construction company were to come in and clear a significant number of the trees? How would it also effect the number of insects and owls? Support.
    Birds would die or eave because of no home then the owls would decrease because of limited food. Insects would increase.
  35.                  If the population of owls decreased, would the Lynx population be greatly affected? Why or why not?
    The lynx population wouldn't be greatly affected because of its other food chains.
  36.                  If the elk and moose population were reduced because of hunting, how would the wolf population be affected? Explain.
    The wolf population would decrease greatly because of limited food.
