Question

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

Explanation:

As shown in the table, in commensalism, Species A has a neutral effect while Species B has a positive effect. This matches the description of one species having a positive outcome and the other a neutral one. Parasitism has one positive (parasite) and one negative (host). Competition has both negative. So the correct answer is commensalism.

Answer:

C. commensalism
