One example of ecological interaction in the ocean is the relationship between boxer crabs and sea anemones. in this unique relationship, the crabs "wear" the stinging anemones on their claws as an extra level of protection from predators. the anemones are then free to eat any leftovers from the crab's meal.

part a: identify which type of symbiotic relationship the above example is. (1 point)

part b: in a parasitic type symbiotic relationship, one species of the pair is harmed. make a fictional change to one of the members of the boxer crab/sea anemone relationship so that it becomes a parasitic relationship. describe what that change is. (3 points)

Explanation:

The ecological interaction between the sea anemone and monster crab is said to be a mutualism.

Mutualism is an ecological interaction between two or more species where all the parties benefits.

The sea anemone-boxer crab relationship as described is a mutualism. The anemone provides protection from predators of the crab using its powerful stinging claws. This prevents the crab from enemies. The anemone in return is able to get nutrient from the leftovers of the crab. Both organism serve a need for another and depends on one another for life.

2. For a parasitic situation to surface, one fictional assumption would be that, the boxer crab keeps getting protected by the stinging claws of the Anemone. The boxer crab on the other hand does not leave any leftover behind for the anemone to feed on.

In parasitism, only one specie benefits while the other loses from the relationship. If the boxer crab feeds without leaving any remnants, the sea anemone would get no nourishment. This might hamper the survival of this specie.
