Question 51
Coral reefs are formed by tiny animals called coral polyps. Their hard skeletons provide many different habitats where other species can live.
One of these species is a single-celled alga that makes a toxic substance called ciguatoxin. Herbivorous fish eat the alga. Carnivorous fish eat the herbivorous fish. Humans often eat the carnivorous fish.
