the blank at the aquarium explained how the health of coral reefs affects ocean animals either positively or negatively visitor, professor, ecologist, chemist chose the best word to

Answer 1

The best word to fill in the blank is "ecologist."

So the complete sentence would read: "The ecologist at the aquarium explained how the health of coral reefs affects ocean animals either positively or negatively."

An ecologist specifically studies the relationships between living organisms, including their interactions with the environment, making them the most suitable choice for discussing the health of coral reefs and their impact on ocean life.
