PLEASE HELP! IM DOING MY FINALS QUIZ AND I REALLY NEED A GOOD SCORE TO BRING MY GRADE UP!! :)
Corals are habitat specialists and only like to live in certain places. However, the corals compete with other types of algae, like seaweed, for space to grow. Sarah is a marine biologist who is interested in corals because they are such important animals on the reef. She wanted to understand how to help the dying corals. She thought that when herbivores are present and are eating algae on the reef, the corals in turn have less competition for space and thus more room to grow.
Which of the following is the best testable question for Sarah's observations?
A.What are corals?
B. Do corals perform photosynthesis?
C. Are corals habitat specialists?
D. How does the presence of herbivores affect coral populations?
