Observe ants going on a line. Ask your teacher how they communicate and write a note on this.

Answer»
  • Ants talk to each other using chemical signals called pheromones that they detect with antennae.
  • Ants use their antennas to pick up smells. 
  • For example, when ants find food they have a pheromone trail from the food soure to the colony. 
  • Other ants follow this trial. As the other ants follow the trial, the pheromone scent becomes stronger. 
  • The paired antennas of ants provide information about the direction and intensity of scents. 
  • Since most ants live on the ground, they use the soil surface to leave pheromene trail that may be followed by other ants. 
  • Some ants produce sounds using gaster segments and their mandibles. 
  • Sounds may be used to communicate with colony members or with other species.
