Final answer:
Tribes have decentralized political leadership with power shared among community members. Economic activities are based on mutual cooperation and reciprocity.
Step-by-step explanation:
Tribes are characterized in terms of political leadership and economy based on their social organization. In a tribe, political leadership is typically decentralized, with power shared among all members of the community. Decision-making is often made under the authority of a person holding a inherited political office, such as a chief or king. These leaders consult with community councils and representatives of different groups within the society.
In terms of economy, tribes often rely on subsistence patterns such as gathering and hunting or horticulture. They may also engage in seasonal agriculture or animal husbandry. Economic activities are typically carried out within the community and are based on mutual cooperation and reciprocity.
