2. Complete the following sentences.
(i) An ant is the smallest, the commonest and the wisest

(ii) We know a number of facts about an ant’s life because people
have kept ants as pets, and have watched their daily behaviour closely.
Answer these questions:

complete ant?
Ans- It takes about five to six weeks for a grub to become a
complete ant.

builders, cleaners etc.
4. Name some other creatures that live in anthills.
Ans- Other creatures that live in anthills are beetles, lesser breeds of
ants and the greenfly.
3. In what ways is an ant’s life peaceful?
Ans- Each anthill has hundreds of little rooms and passages. Queen ant
lays eggs in some rooms. Some rooms are nurseries for the young ones. Soldiers
have separate barracks. Some rooms serve as storehouses for this
food. Workers have their reserved quarters.
No worker has ever tried to live in a soldier’s house;
no soldier has ever gone out searching for food. No worker or soldier or
cleaner has ever harmed a grub. Therefore, we can see that an ant’s
life is very peaceful. Each does its share of work intelligently and
bravely, and never fights with other members of the group.

teacher’. Give reasons for choosing these items.

grub.
Care for the young ones- Workers ants feed and clean young
ones, and also carry them about daily for airing, exercise and
sunshine.
