Examine the saturated thickness levels between 1975 and 1990 and between 1995 and 2010. Each of these are fifteen-year spans, but the decrease in saturated thickness is not the same. Even if the population were to stay the same over this time, why do you think the drop in thickness is not as great?

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
