Question

There are two different species of finch that live on the same small island, species A andspecies

b. Both species successfully feed and reproduce on the island. Species A nests inpine trees and eats large seeds. Species B nests in hollowed-out dead logs and eats smallinsects.Both bird species A and species B can most likely survive on the same small island because they(1) use different resources and, therefore, they do not compete(2) mate with each other, keeping both populations constant(3) compete for food, but do not compete for shelter(4) eat the same food, but feed at different times of the day

Answer 1

On the islands of the Galapagos lives a group of birds called finches. There are 13 species in this group. These species have diverse ecologies--some eat seeds, some eat insects, some eat fruit, and some even eat cactus. Although the bodies of these species look fairly similar, their beaks are very different. That is because it is their beak that is adapted to these diverse ways of feeding (Figure 8.14).
