Communication is any form of behavior that send a signal to any other organism. Gestures, facial expressions, gazes, or chemical signals are examples of communication through animals. For example ants use a chemical signal called pheromones, they use this to show paths to food, alarm calls, mate attraction, and to distinguish between colonies. Ants, bees, and termites all use pheromones.
