Answer:

Evolution

Explanation:

If there is an environmental stressor, then animals will evolve to overcome it.

Birds may begin producing more or fewer offspring depending on how much food is available. If there is more food available, birds will have more offspring. If there is less food available, birds will produce fewer offspring.

Beak characteristics change depending on food options, mating rituals, or environment. A bird will need a narrow beak for most bugs, but it will need a wider and stronger beak for nuts and seeds. A bird's beak may also be used to help interact with its environment. For example, a woodpecker has a strong narrow beak to help it break into tree bark to eat.
