Solution

Question-

Whether the orientation of dinoflagellates P. noctiluca and L. polyedrum contribute positively the first strike capturing ability of the fish and the shrimp or not?

Answer: on the basis of graphs, this is clear indicating that more orientation of dinoflagellates makes feasibility to strike them by their predators, especially in the night duration.
