What are 2 habitats that exist in the nertic zone?
Coral reefs and kelp forests
Briefly describe a coral reef.
its a habitat that is created by coral animals. It provides a place for lots of other organisms to live. It grows in warm shallow water
Briefly describe a kelp forest
occurs in cold neritic water where there is a rocky bottom. its home for sea slugs, sea urchins and a hiding place for whale young
