in some cases two species are so dependent upon each other that if one becomes extinct, the other will as well. this nearly happened with trees that relied on the nowextinct dodo birds. ① they once roamed mauritius, a tropical island situated in the indian ocean. however, ② they became extinct during the late 19th century. ③ they were overhunted by humans and other animals. after ④ they disappeared, the calvaria tree soon stopped sprouting seeds. scientists finally concluded that, for the seeds of the calvaria tree to sprout, ⑤ they needed to first be digested by the dodo bird.
