Touch and Smell
Ants use chemical signals to tell each other about food and a number of other things like enemies.
It is their mode of communication about movement,procurement of food etc. that ants touch each other while passing in a row.
Ants use chemical signals to impart information to each other. This can be information is generally about food or predators. When you see them following each other they are following a chemical trail not the ants in front of them.
follow me i found the food sourse
True but they do it with chemicals and smell, not the way we do. They mark a trail with a pheromone to the food with their abdomens. They have other chemicals to indicate other things as well, like an attack on the colony, etc.
Ants are able to find food by communicating with each other. They use they pheromones to direct each other on where the food would be.
Ants work together in a colony by each ant having their own job. There are ants that gather food, there are scout ants that find food for the other ants to gather. There are also warriors who attach other nests and defend their own nest and queen.
it brings food to the other ants
Ants leave a trail with pheromones, which are chemical signals that they excrete as they move. These pheromones help other ants follow the trail to food sources or to communicate with each other.
Ants produce chemical compounds such as formic acid, which they use for defense and communication. They also secrete pheromones to communicate with each other and mark trails to food sources. Additionally, their exoskeletons contain chitin, a polymer made of sugar molecules.
