Make two food chains/webs illustrating the before and after situations. Including what happened to the populations.

How Important to biodiversity are Wolves?

Wovles who hunt for Elk and pick out the weak or Injured. By lowering the Elk population the more vegitation for the rest of the Elk. Since the wolves got reintroduced to yellowstone they hunt the Elk and Bison. Leaving the scraps for the scavengers (Coyote, Birds). Creating the balance in Yellowstone's ecosystems.

Actions Wildlife managers did to make changes?

Before there were any wolves in Yellowstone the elk population grew to big and food for scavengers was hard to get. So Wildlife managers brought back the Wolves to create the nessasary balance to Yellowstone's ecosystems.

If there were no wolves in Yellowstone other species would grow to big and if there were to many wolves evencually there would be no elk so no food for wolves or scavengers.
