Question

which symbiotic interaction involves behavior that is positive for one species but is neutral for the other? competition mutualism commensalism parasitism

Explanation:

• Competition: Both species are negatively affected (e.g., fighting for resources), so this is incorrect.
• Mutualism: Both species benefit from the interaction, so this is incorrect.
• Commensalism: One species benefits, and the other is neither helped nor harmed (neutral), which matches the description.
• Parasitism: One species (parasite) benefits, and the other (host) is harmed, so this is incorrect.
