On an island, finches that fed on large, hard seeds had large beaks. Finches with small beaks fed on small, soft seeds. A drought changed the

vegetation on the island. After this period, the number of seeds declined. The decrease in small, soft seeds was greater than the decrease in

large, hard seeds. What are two ways the decrease in seed availability will affect the population of birds on the island?

The population of birds with large beaks will increase on the island.

The population of

ds with small beaks will increase on the island.

The trait for large beaks will be passed on to future generations through natural selection.

The trait for small beaks will be passed on to future generations through natural selection.

The population of birds with large beaks and birds with small beaks will be equal on the island.

The correct answers are "The population of birds with large beaks will increase on the island" and "The trait for large beaks will be passed on to future generations through natural selection".

Explanation:

Natural selection functions under the premise of survival of the fittest, where stressful situations such as lack of resources will select the organisms with advantageous traits. In this case, the decrease on seeds affected particularly the numbers of small, soft seeds over large, hard seeds. This stressful situation will select the finches with the advantageous trait of having large beaks, because they are able to feed from large, hard seeds. This trait will be passed on to future generations through natural selection, which eventually will result in the population of birds with large beaks will increase on the island.
