You visit a medium-sized Caribbean island and identify 4 species of anole lizard. Consider the 3 possible scenarios below. You return to the island a number of years after each of these scenarios. Explain which outcome below (i to iii) you expect for each scenario and briefly justify your prediction. (2-3 sentances) (i) An increase in the number of anole species (ii) A decrease in the number of anole species (iii) No change in the number of anole species Scenario A: Scenario A: A new virus is introduced, which causes all the anoles to become colour blind. Scenario B: An earthquake separates the island into two islands. Scenario C: An invasive herbivorous insect species is introduced to the island, which devastates many plant species and causes the habitat to become much less complex.
