- Coral reefs are unique, living structures. Even though they appear to be hard, rock-like structures, the soft-bodied coral animals that build the elaborate, hard, rock-like reef structures around themselves live inside. Corals are unique animals because they have photosynthetic algae that live inside their cells. This unique relationship is beneficial to the algae since it has a safe place to live inside the coral cells, and it is beneficial to the coral since the algae are producing food via photosynthesis. From the description above, what type of symbiosis is described, and at what ecological level does this relationship exist? The relationship is an example of parasitism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the community level.
