D) When corals are babies floating in the plankton, fish swim with them and protect them from harm.
Explanation:
This is the statement that does not explain how fish and coral relate to one another. It is false that when corals are babies, fish swim with them and protect them. However, the rest of the statements are true. It is true that fish eat predators, and that they also eat seaweed and kelp that could smother the coral. Finally, it is also true that some fish live symbiotically with coral, luring prey for the coral to kill and eat.

The possible result of the founder effect would be loss of genetic variation. The reason why this is so is because by definition, the founder effect is often considered to be the cause for a essened genetic variation in a specie or a certain area where organisms thrive.
