DICTATION 4

       Social insects live in integrated communities which in some ways are similar to human communities. In both types of community there is division of labour. In insect societies certain insects are responsible for reproduction; the workers collect food while the soldiers defend the colony. In the same way human groups such as farmers and shopkeepers have specialized functions in producing goods and providing services to the community.

       Insect and human societies are also alike in that individual members of the community work together. Ants coordinate their efforts to build nests. Similarly, in human societies engineers, architects, town planners and construction workers unite to build cities.

       The nests of social insects are as complex as a man-made city. In some insect nests special accommodation is provided for the young and for food storage. Many nests also have devices for regulating the temperature. So insect nests are as functional as human houses.
