Evolution: Change Over Time


Correct Answer: Option 4 There is increased competition for a limited number of small seeds

Whenever food is scarce, and there is a high demand for food, the competition for accumulating that food will increase in order for the population to survive.

Option 1 is incorrect because the primary goal of the birds is to survive.

Option 2 is incorrect. The birds with large beaks will not have a change in food preference because their nutrition source is not at risk. Only small seeds are scarce during dry season. They can still eat the large seeds because of the size of their beaks.

Not all finches will be affected by the dry season and parasitism is not a characteristic of finches. Thus, option 3 is incorrect.
