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?
a). the population of birds with large beaks will increase on the island.
b). the population of birds with small beaks will increase on the island.
c). the trait for large beaks will be passed on to future generations through natural selection.
d). the trait for small beaks will be passed on to future generations through natural selection.
e). the population of birds with large beaks and birds with small beaks will be equal on the island.
