B. all of the members of the species would make do with the existing cacti on their new island.

C. the entire species would go extinct.

D. most of the members of the species would die but some would survive.

Study the image of the fossil shown below. How might a scientist use this fossil to learn more about the history of life on Earth?

    It's D because Charles Darwin had a theory while studying them on the Galapagos Island that even though lived in the same places, their beaks were fully different from each other because the beaks were acquired for the food their were eating. If this happened, then in the first month many of the finches wouldn't adjust and die but few will adjust and have offspring that will have beaks specially for that too.
