Verified step by step guidance1
Step 1: Begin by understanding the definitions of the relationships provided in the problem. Commensalism is a relationship where one organism benefits while the other is neither helped nor harmed.
Step 2: Define mutualism. Mutualism is a type of symbiotic relationship where both organisms involved benefit from the interaction.
Step 3: Define parasitism. Parasitism is a relationship where one organism (the parasite) benefits at the expense of the other organism (the host), which is harmed.
Step 4: Define predation. Predation is a relationship where one organism (the predator) hunts and kills another organism (the prey) for food, benefiting the predator but harming the prey.
Step 5: Compare the definitions and identify mutualism as the correct answer because it is the only relationship where both organisms benefit.
