Use the following passage to answer the next 5 questions. You are studying the intertidal zone of a previously unstudied island. You find three species of barnacles on the rocks. Species A is most abundant in the upper intertidal zone, Species B in the middle, and Species C in the lower, as shown below. Species A dominates Species B dominates Species C dominates Upper intertidal zone Middle intertidal zone Lower intertidal zone
Submit Q9. Remember that Species B is more abundant than the other two species in the middle intertidal. Both Species A and B settle in that range at the same rate and both survive in that zone equally well when the other is excluded. You conduct a transplant experiment similar to that in question 8, transplanting multiple rocks, each with 10 individuals of Species A, into the middle intertidal zone. You count the number of individuals of each species present at the end of 30 days. Based on your findings below, what can you conclude? Number of individuals, after 30 days, on rocks transplanted to the middle intertidal zone. ROCK Rock 1 Rock 2 Submit Rock 3 A 8 10 7 SPECIES B 8 7 10 с 3 0 1 Species B outcompetes species A in the middle intertidal zone. Species B has better adaptations to the physical environment of the middle intertidal zone than does Species A. The presence of Species C in the samples means that no conclusions can be drawn. Neither competition nor differences in adaptation to the physical environment alone explain the distributions of Species A and B.
