Verified step by step guidance1
Understand the definitions of the relationships provided in the options: Mutualism, Commensalism, Parasitism, and Competition. Mutualism is a relationship where both species benefit. Commensalism is a relationship where one species benefits and the other is neither harmed nor helped. Parasitism is a relationship where one species benefits at the expense of the other. Competition occurs when two species vie for the same resources.
Analyze the interaction described in the problem: A pseudoscorpion is dispersed by a harlequin beetle. This means the pseudoscorpion benefits from the beetle's movement, as it gains transportation to new areas.
Determine whether the harlequin beetle is harmed, helped, or unaffected by the pseudoscorpion. In this case, the beetle is unaffected because the pseudoscorpion does not harm or provide any benefit to the beetle.
Match the interaction to the correct type of relationship. Since the pseudoscorpion benefits and the beetle is neither harmed nor helped, this fits the definition of commensalism.
Conclude that the correct answer is commensalism based on the analysis of the interaction and the definitions of the relationships provided.
