Mo5-L3b: Why Traits Change?




        Extinction and Conservation Biology               Organisms called invasive
                                                          species may be introduced
        When the last individual of a species dies, the    into a habitat, making it
        species has undergone extinction.                 difficult for some native
                                                          species to survive and
                                                          reproduce.


                                                          Conservation biology is a branch of biology that
                                                          studies why many species are in trouble and what
                                                          can be done to save them.

                                                 Why Traits Change?

                                  Conservation biologists work to save species
                                                 from extinction.
