Answer 2

The correct answer is - A. Coral reefs ecosystems are typically in shallow water, and demersal ecosystems can exist at any depth.

The coral reef ecosystems are found on places where the water is shallow, which is why they can be usually found near the coastlines. They also prefer warm water to develop and exist, thus are usually in between the equator and the mid-latitudes.

The demersal ecosystems, on the other hand, are located just above the seafloor. Depending on the depth of the ocean, sea, or lake, that can mean that this ecosystem can be found anywhere from relatively shallow water to extreme depths. Because of this, the demersal ecosystems vary in what type of organisms they can support, as they can be in waters where sunlight penetrates, or in waters that the sunlight can not reach.
