The best comparison between the coral reef ecosystem to the demersal ecosystem is:

Coral reef ecosystems may have starfish, clams, and other invertebrates, and demersal ecosystems have only fish.

The demersal zone is located near the bottom of the sea or ocean. It is above the Benthic zone and is only inhabited by two types of fish. These are the fishes that are too heavier than water and needs to rest on the seabed and those that can stay just above the substrate due to its neutral buoyancy.
