Reproductive strategies unit test U5 Lesson 8

A species of bird has slight variations in its beak size and shape. Some individuals with bigger beaks are better at cracking seeds. Some individuals with narrower beaks are better at hunting for bugs. An invasive species is introduced that hunts all of the bug population, wiping out that food source for the birds, so all they are left with is seeds.

In one to two sentences, explain how genetic variation from sexual reproduction can save this species from extinction.

Can some one help me not with an answer but just put me on a path to get a good grade

Answer 1

To answer this question and get a good grade, you need to understand the concept of genetic variation and how it relates to survival in changing environments. Start by reviewing information on sexual reproduction, genetic variation, and adaptations in species. Then, consider how the variation in beak size and shape in the bird population could lead to different abilities in seed-cracking. Finally, think about how this genetic diversity could give the species a chance to adapt and survive in the absence of their primary food source, bugs. By understanding these concepts and applying them to the specific scenario, you will be able to provide a well-informed answer that showcases your understanding of the topic.
