Final answer:
Individual ants of the same species use pheromone trails to indicate the path to different food sources or back to their own colony. This behavior is an example of communication among social insects.
Step-by-step explanation:
The behavior described, where individual ants of the same species use pheromone trails to communicate and indicate the path to different food sources or back to their own colony, is an example of communication among social insects. This behavior allows ants to cooperate and work together towards a common goal. Through the use of chemical signals called pheromones, ants can effectively guide each other to food sources and coordinate their activities as a colony.
