Suppose that a species of bird lives on an island in the Pacific Ocean. Most of the birds nest on the ground, but some nest up in trees. Nesting in trees is a hereditary trait. During a storm, a pregnant pig washes up on the island. The pig starts to eat everything she finds on the ground, including the ground-nesting birds. She has 10 piglets and all of them also eat any birds they can catch. How would the process of natural selection most likely affect the birds in this environment? a. The ground-nesting birds might start to produce extra offspring to make up for the ones eaten by the pigs
b. The ground-nesting birds might move into the trees to nest
c. The-tree nesting birds might survive and reproduce surviving offspring because the pigs cannot reach them
d. The tree-nesting birds might produce fewer eggs to reduce competition for nesting space
