Final answer:
Redistribution is the prevalent exchange system in chiefdoms, where wealth is centralized by chiefs and used for government and community services.
Step-by-step explanation:
The type of exchange system that is more prevalent in chiefdoms is redistribution. Redistribution is a process where wealth is centralized and controlled by leaders such as chiefs, who then use it to finance various aspects of government and social services. This system was particularly dominant in agricultural societies with hierarchical structures. For example, in precolonial Hawaii, chiefs would receive tribute from commoners which would then be used to provide community benefits like social order and construction of public works. It supports not only the functioning of the society but also the status and power of the chiefs, serving both an economic and a social purpose.
