Another aspect of the competitive exclusion principle is that animals that compete within the same environment may eventually come to occupy their own NICHE. A niche is a way of life, and includes how the animal lives, what it eats, reproduction strategies and more. For example, a hawk and owl both eat the same kinds of food, but the owl hunts at night and the hawk during the day. How did your final ecosystem?

Both hawk and owl share the same habitat or ecosystem.

Explanation:

According to competitive exclusion principle, two species can't coexist in the same environment if they occupy exactly the same niche but in the case of hawk and owl, it is possible because both have different times of eating habits. Hawks hunts at daytime while on the other hand, an owl hunts at night so both share the same habitat due to difference in their niche and they are present in the same ecosystem.

because all cells have genes

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
