The other thing is that coral reef ecology could be very interesting; it would discuss complex and diversified systems in the coral reefs. Rich in life, so many species dwell and add to their health and stability within the underwater habitats. The very ecosystem of the coral itself is already a complex web of interactions among corals, fish, invertebrates, and algae, all taking part for the balance of this underwater habitat.

This renders corals a rather fragile ecosystem and, thus, an indicator of the health of oceans. Corals form a class of marine invertebrates that live under conditions where there are clear, shallow waters allowing sunlight to penetrate for photosynthetic algae contained in the tissues of the corals. As a payback, these algae provide the corals with critical nutrients through photosynthesis, which empowers them to build their calcium carbonate skeletons that essentially make up the structure of the reef.

These ecosystems, being very bio-diverse, are of great importance for resources and services, including fisheries, tourism, and protection and conservation of the shoreline. However, there are several threats these reefs have to face which can disrupt the typically delicate balance of these ecosystems in response to climate change, pollution, overfishing, and other such stressors.
