Answer:
Mutualism
Step-by-step explanation:
Mutualism is the symbiotic association between two organisms in which both the partners are benefited. In the given example, the boxer crab uses the stinging tentacles of anemone to protect itself from the predators. On the other hand, the anemone is benefited by feeding on the particles from the prey caught by crab. Since both crab and anemone are benefited, it is an example of mutualism.
