How does symbiosis differ from other forms of species interactions?
What will be an ideal response?
Symbiosis is a relationship in which two species benefit from living together in intimate contact. The relationship between corals and plant-like protists known as dinoflagellates is a good example of a symbiosis. This symbiotic relationship involves a beneficial cooperation between the coral animal (polyp) and a dinoflagellate that lives within the digestive cavity of the coral polyp. The coral provides protection, inorganic nutrients through excretion, and carbon dioxide for the dinoflagellate. In turn, the dinoflagellate provides nutrition (photosynthate), helps the coral synthesize some organic compounds (lipids), and removes carbon dioxide, making it easier for the coral to precipitate its CaCO3 skeleton.
