Chapter 1: Super Senses

Think and Tell

Question 1: How did the ant know that the other ants were not from its group?

Answer : Ants use their highly sensitive antennas to identify the members of their group. The antennas of an ant possess the sense of both smell and touch. These antennas help them to smell five times better. So, this is how the ant got to know that the other ants were not from its own group by using its antennas.

Question 2: How did the guard ant recognize this ant?

Answer: The guard ant could recognize and identify this ant by its smell.

Answer: The ants climb up on the pencil. However, we see that they still continue to move in a line.

Question 7: Now can you guess why the ants behaved like that when you blocked their path?

Answer: Ants actually leave a special smell on the ground while they are moving from one place to another. The other ants track this smell in order to find their way. Thus, when their path was blocked, the ants maintained their path by using their sense of smell.

Question 8: Have you ever been troubled by mosquitoes? Just think, how do they know where you are?
