Chlorophyll is involved in the biochemical process of photosynthesis. during this process leaves absorb light energy and convert it into chemical energy known as glucoses which is used by the plant. this is the reason why leaves are green and other parts such as roots are not.

Is this a true or false, because it is true, because the leaves capture sunlight, they use it to emit oxygen and sugars for our respiratory system.

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.
