Would species do you think would have a larger population in a mature forest A animal that eat grass or an animal that eat nuts?

In a mature forest, an animal that eats nuts is likely to have a larger population than one that eats grass. This is because mature forests typically provide abundant sources of nuts from trees, which can support a more stable and diverse food supply. Additionally, animals that eat nuts often have adaptations that allow them to thrive in forested environments, while grass-eating animals may be less common in areas dominated by trees and shrubs.
