1.     Bull Shark- a top predator- affects the number of dolphins, fish, and other small sea animals.

2.     Plankton- the main producer of the Neritic Zone. Without this, populations of fish would be small.

3.     Sponges- some have a mutualistic relationship with algae. They provide carbon dioxide for the algae, while the algae provides oxygen for it.

4.     Seaweed- the second major producer of the Neritic Zone.

5.     Fish- sharks prey on all the different species. If all fish suddenly disappeared, the food web would be greatly affected.
