Question

which term refers to a change in one species that results from a change in another species that it interacts with?
○ coevolution
○ commensalism
○ symbiosis
○ interaction

Explanation:

To solve this, we analyze each option:

• Coevolution: Defined as the reciprocal evolutionary change in two or more species interacting, where a change in one species drives a change in the other it interacts with. This matches the question's description.
• Commensalism: A symbiotic relationship where one species benefits and the other is unaffected, not about reciprocal evolutionary change.
• Symbiosis: A general term for close species interaction (mutualism, commensalism, parasitism), not specifically about evolutionary change due to interaction.
• Interaction: A broad term for species' relationships, not specific to evolutionary change from interaction.

Answer:

A. coevolution
