When an organism receives a reinforcer each time it displays a behavior, it is reinforcement?

This is continuous reinforcement, as opposed to intermittent reinforcement. The reinforcers can be apportioned based upon a fixed ratio (after every "x" responses, for example) or a fixed interval (every "x" seconds, minutes, days, or other time frame). As with any type of reinforcement, this can be either positive (in which something is given to the learner) or negative (in which something is removed from the learner).
