I’m working on a environmental science practice test / quiz and need a sample draft to help me study.
The Textbook( (Environmental Science:Toward A Sustainable Future,13 thedition,
Richard T.Wright and Dorothy F.Boorse)
In Chapter 4 of the textbook,you learned about community interactions in ecosystems and the importance of predators in the top-down regulation of species. Watch the videos at the links above about the importance of wolves in Yellowstone National Park. In a well-written essay of a minimum of 500 words, answer the following questions:
1. Why were predators allowed to be hunted in the federally protected national parks, and what were the effects of the over-hunting of wolves in Yellowstone? (2 points)
2. What happened to the ecosystem when wolves were returned to Yellowstone? How did this affect plant-herbivore dynamics in Yellowstone? (3 points)
3. Imagine that your Congressional representative is supporting a bill to allow for the hunting of wolves in Yellowstone National Park. Based on your knowledge about predator-prey dynamics, what would you say to convince her that it would be extremely damaging to the Yellowstone ecosystem? (5 points)
