Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the United Kingdom. These organisms are unique because they can undergo a special chemical reaction at night that helps defend them against predators. It provides defense by attracting larger predators that prey on the organisms that eat Ceratium fusus . Which characteristic of Ceratium fusus is being described?
The clue is that Ceratium fusus produces light at night. This is bioluminescence, a chemical reaction that emits light and can attract predators of the organisms that eat it. Photosynthesis uses light to make food, while chitin and glass-like walls describe cell structures.
