Check all the ways that corals are fragile.

• They are very productive

• Pieces can break off easily

• They are very sensitive to changes in water quality

• They are sensitive to changes in pH levels.

• They make lots of food and oxygen for the reef.

Reef inhabitants include

• parrot fish, butterfly fish, sponges, worms, sharks

• sharks, sea stars, people, dogs, moray eels

• parrot fish, butterfly fish, sponges, cats

This example of surviving the reef is
