Impact of Wolves in Yellowstone Wolves are an important predator in Yellowstone National Park. When wolves were removed, the elk population grew too large. The elk ate too many trees and shrubs. The lack of shrubs and trees meant the bird population went down, as they needed the shrubs and trees for their habitat Later, when the wolves returned and were able to decrease the elk population, the numbers of trees (like the cottonwood tree) and shrubs were able to increase. When the trees and shrubs increased, the bird populations grew. The birds and the trees help each other. The birds help scatter seeds for new trees, while the trees provide shelter for the birds Consider the data shown in the graph below. 7. Thinking about the graph below, what argument can be made regarding the relationship between the changes to the songbird habitat and the population of songbirds?
O Habitat availability and songtind population are not related When habitat availability is increa reased songbied population goes down. When habitat availability is decre lecreased, song songbird population goes up. When habitat availability is increased, songbird population goes up
