Explain one example of how a feedback control system functions in a particular symbiotic relationship

Symbiotic relationships refer to organisms living in symbiosis. This is a relationship in which an organism lives on, near, or in another organism. An example of how a feedback control system functions in a symbiotic relationship is the relationship between algae and coral. Algae are photosynthetic organisms that live within the hard coral ... the coral gets food from the algae while the coral and its hard covering provides shelter and protection for the algae.
