Transcript

  • 1. Launch Give an explanation to what is happening in the above graph that shows a cow population? (where the arrow points)
  • 2. Catalyst Review
    • Remember that if a population goes over the carrying capacity there are not enough resources to support it
    • What happened in this case was that there were too many cows which ended up eating ALL the grass and not allowing enough to regrow so the population actually declined below the carrying capacity.
