Explanation:
Coral reefs are the structure which are one of the some most important underwater ecosystems of the world. They are characterized by the formation of roof-building corals which are basically the colonies of dead or living polyps(corals) attached together through deposition of calcium carbonate.
Red algae has an important role in the formation of coral reefs because their thread like structure traps the particles present in the sand of water which ultimately gives the algae a mechanical support for their growth as well as the formation of coral reefs.

Hi there!
By both unity and diversity in life, it means that animals and plants (and ecosystems) can be very different from each other but they can also have very similar characteristics. They can work together in harmony but become predator and prey at the same time.
Hope this helps!
