Based on your observation and your experimental design, What do you predict will happen? Recall that you are counting the algae that are left in the coral, not the algae that is expelled.
1) The coral in the 87 degree tank will have less algae left in its tissues after two weeks
2) The coral in the 87 degree tank will have the same amount of algae left in its tissues after two weeks
3) The coral in the 87 degree tank will have more algae left in its tissues after two weeks
