Today you will do some research on Yellowstone National Park. Yellowstone is a unique national park located in Northwest Wyoming. I would like you to research what happened to the wolf population in Yellowstone and how that affected its homeostasis.

  1. What happened to the wolf population in the last 100 years?
  2. What happened to the elk population as the wolf population decreased?
  3. What happened to the vegetation as the elk population increased?

In short, you will research the necessary conditions for Yellowstone to remain at homeostasis and explain what they are.

Vocabulary to include: population, feedback loop, homeostasis, keystone species, wolf, elk, carrying capacity.
