  1. If there are too many limiting factors on a population what could be the end result for that population?

  2. A squirrel has many environmental factors that can affect whether it survives or not. List 2 abiotic factors and 2 biotic factors.

  • Biotic: food source, competition
  1. Acceptable answers include, but are not limited to:
  • The carrying capacity of the area is 20. That means that there are only so many resources available for the squirrels therefore it limits the population to no more than 20.
