Answer:
b. Dinoflagellates provide nutrients from the products of photosynthesis which are essential for zooxanthellae survival.
Explanation:
The endosymbiotic dinoflagellates are found in the bodies of corals. These endosymbiotic dinoflagellates are called zooxanthellae and are immobile. Being autotrophic, zooxanthellae carry out photosynthesis to produce the organic food required for corals. Death of endosymbiotic dinoflagellates deprives the coral of organic nutrients leading to their death. This is why the endosymbiotic dinoflagellates are required for survival and productivity of coral reefs.
