Question

which symbiotic interaction involves two organisms in which both benefit in a positive way? mutualism commensalism competition parasitism

Explanation:

To solve this, we analyze each symbiotic interaction:

• Mutualism: Both organisms benefit.
• Commensalism: One benefits, the other is unaffected.
• Competition: Organisms compete for resources (negative for at least one).
• Parasitism: One benefits (parasite), the other is harmed (host).

So the interaction where both benefit is mutualism.

A. mutualism
