Answer:
Ants are the most interesting of all insects because they are so much like human beings in many ways. They live in families, build their own houses and have a king and a queen. Each ant has its own work to do, and it does its work well. When the very young ants are older and their skins are harder, they are ready to leave their nest and do other kinds of work. Some of the ants hunt for food. Most other insects go about looking for food, but it is always for themselves whereas the ants think of the nest. They bring food for the queen and other workers as well as for themselves.
