Feedback and Bee Stings

Negative feedback opposes change and restores stability. Positive feedback amplifies a disturbance's effects. Both types of feedback control a disturbance and may occur within the same system. A predator receives a bee-sting. If he moves away from the hive, it is negative feedback. But if the disturbance continues, angry bees may entice others to sting, until the entire colony emerges stinging. If the predator and the angry bees all die, together they have displayed positive feedback.
