How did the ant know that the other ants were not from its group?
The ant had antennae to sense smell. With the help of the smell, it came to know that the other ants were not from its group.
Drop some sugar, jaggery or anything sweet on the ground. Wait until the ants come there.
Now carefully, without harming the ants, block their path for a while with a pencil.
Now observe, how do the ants move?
