A-behavior

Explanation:

If you are responding to something, you are behaving depending on what it is that is triggering you to respond to that current situation. Think of it this way, you've lost your phone, you are reacting to it with panic (behavior), or you made the last goal and are exited (also behavior). What ever you or the organism is reacting to depends on how you react to it, whether it an oh no, or a I GOT IT, your behavior adds to how you react.
