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 term:

• Coevolution: Defined as the process where two or more interacting species evolve in response to each other's changes. This matches the description of a change in one species due to a change in an interacting species.
• Commensalism: A symbiotic relationship where one species benefits and the other is neither helped nor harmed. It does not involve reciprocal evolutionary change.
• Symbiosis: A general term for close and long - term biological interactions between different species. It is a broader category and does not specifically refer to evolutionary changes in response to each other.
• Interaction: A very general term for how species affect each other. It does not imply evolutionary change as a result of the interaction.

Answer:

A. coevolution
