Final answer:
Redundancy trade was important in the Plains trading system for diversification of goods, mitigation of scarcity, and fostering social and cultural exchange.
Step-by-step explanation:
Redundancy trade, such as trading com for com and moat for meat, was an important part of the Plains trading system for several reasons. Firstly, it allowed for the diversification of goods and ensured that communities had access to a wide range of essential resources. For example, trading com for com allowed different communities to exchange surplus corn, which was a staple crop in the region. Similarly, trading moat for meat ensured that communities had access to both grains and protein, which were crucial for survival.
Secondly, redundancy trade helped to mitigate the risk of scarcity by creating a network of interdependence among different tribes and communities. If one community faced a shortage of a particular resource, they could rely on other communities to provide it through trade. This helped to ensure a more stable and resilient trading system.
Finally, redundancy trade also facilitated social and cultural exchange among different tribes. Through trade, tribes had the opportunity to interact, learn from each other, and establish social ties. This had the potential to foster cooperation, resolve conflicts, and strengthen intertribal relationships.
