Which algae take part in the formation of coral reefs along with coral animals?
Correct answer: A. Red
- A. Red
- B. Brown
- C. Green
- D. All of these
Explanation
The correct answer is Red algae. Red algae, especially coralline algae, play a significant role in the formation and stabilization of coral reefs by depositing calcium carbonate, which helps build the reef structure. Brown and green algae, while present in marine environments, do not contribute to the actual formation of coral reefs in the same way. Option D is incorrect because not all types of algae are involved in reef formation.
