Frog lungs are poorly developed. how does this relate to their skin being thin and moist

It relates to it because the frogs can breathe through their skins. We can too but it's not developed because we don't need it, but skin has pores for perspiration as well and transpiration. Frogs however don't have developed lungs like we do so they get a lot of the oxygen using their skins because they had to develop this system or they would not exist today.

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.
