Answer

Brief Explanations:

The question addresses the impact of resource scarcity on biological populations, specifically Darwin's finches. When primary food sources like seeds and nuts decrease indefinitely, the overall carrying capacity of the environment drops, leading to a general decline in all finch populations due to starvation and increased competition. Furthermore, if the remaining seeds are likely the tougher, larger ones that were not consumed first, finches with larger, stronger beaks possess a selective advantage to crack them, making them more likely to survive than those with smaller beaks. Options b and c are incorrect because they suggest the opposite of natural selection trends in this context, and option d is an behavioral change that cannot be assumed without specific evidence of insect availability.

Answer:

a. All populations of finches on the island will decrease. e. Populations of finches with larger beaks are more likely to survive than finches with smaller beaks.
