Question 45
A study was conducted on the seed-eating finch population on the Galápagos Islands. It was observed that when rain was plentiful, the plants produced many small, soft seeds. During periods of drought, only a few small, soft seeds were produced. These were usually eaten by other animals before the finches could get to them. The seeds that remained were large, dry and hard.
Another species of finch eats berries. Do you think this species would have been similarly affected by the changes in rainfall patterns? Give a reason for your answer.
