Question

Ants usually go in a line to reach sweet kept in the tin. How do they know the way to reach the tin ?

Answer 1

Hint: They communicate with one another using certain chemical messengers. They sense the smell of food using their long, thin, and mobile antennas attached to the top.

Complete answer:
Ants communicate with one another using pheromones (chemical messengers), sounds, and touch. The utilization of pheromones as chemical signals is more developed in ants. Ants recognize smells with their long, thin, and mobile antennae. The paired antennae supply information about the direction and intensity of scents.
Since most ants survive on the ground, they use the soil surface to go away pheromone trails which will be followed by other ants. In species that forage in groups, a forager that finds food marks a trail on the way back to the colony. This trail is followed by other ants, these ants then reinforce the trail once they head back with food to the colony.
The pairs are attached to the top, which detects chemicals, air currents, and vibrations. They also want to transmit and receive signals through touch.
Some ants produce sounds by stridulation (act of manufacturing sound by rubbing together certain body parts), using the gaster segments and their mandibles. Sounds could also be wont to communicate with colony members or with other species.

Additional Information:
Animals secrete pheromones to trigger many sorts of behaviours, which incorporates the following:
- Raising an alarm - Signaling a food trail - Triggering arousal - Tell other female insects to get their eggs elsewhere - Delineating a territory - The bond between mother and offspring

Note:
A pheromone may be a secreted or excreted chemical factor that triggers a social response in members of an equivalent species. Ants form colonies that home in size from a couple of dozen predatory individuals living in small natural cavities to highly organised colonies which will occupy large territories and contains many individuals.
