What builds up over time to form a reef?

• Sand

• Coral skeletons

• Fish bones

Coral bleaching is:

• an overgrowth of algae

• when coral polyps reject the zooxanthellae living inside

• a disease that attacks coral

• how marine biologists clean up the coral

Coral Reefs are found in shallow, clear, warm water because there is

• lots of sunlight for the symbiotic algae (zooxanthellae) that live with the polyps

• not lots of sunlight for the symbiotic algae (zooxanthellae) that live with the polyps

• no good reason, it just feels nice

• all of these choices are correct

• calcium carbonate

• calcium manganese

• carbon monoxide

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.

A coral reef is made up of thousands of small structures called

• sea stars
