Over time, the food supply for birds on an isolated island has changed. The supply of insects, small tender seeds, and vegetation has shrunk. The supply of tough, large, hard seeds has remained unchanged. Over several generations, changes in genetic traits of birds' beaks have occurred. Which beak is most likely to improve the survival rate of the birds?

The spider plant (Chlorophytum comosum) is a viviparous plant. This means that seeds germinate into small plantlets while still attached to the parent plant. This plant also produces small white flowers on arching stems. The flowers develop into small seed pods and then the plantlets develop on the stems. Being a viviparous plant is an advantage to the spider plant in which of the following ways?

• Grazing animals are not attracted to the small white flowers.

• The plant and the plantlets are not in competition for limited rainfall and light.

• The plantlets are genetically different from the parent plant and are not affected by the same insect or pesticide problems.

• The plants do not have to rely on animals, insects, or wind for pollination or seed dispersal.
