Answer:
1. Ants, termites, and bees
Explanation:
Eusocial societies are common in insects. This type of behaviour is characterized by the fact that individuals fall into certain groups with certain behaviours. For example, think of worker bees and the queen bee. These societies are associated with a few features:
- the offspring are cared for by individuals other than the parents -many members in the group can cooperate to take care of the young.
- labour is divided into reproductive and non-reproductive groups. Only the reproductive individuals are able to have offspring, the others help with parental care, gathering food, and maintaining shelter.
- this creates groups, sometimes called 'castes', that animals fall into. They do not deviate from these groups once they are established.
