Final answer:
The Native Americans' food sources included hunting for pronghorn and bison in the Great Plains and cultivating crops such as maize, squash, and beans in both the southwest region and the Great Plains.
Step-by-step explanation:
The Native Americans had various sources of food, depending on their region and lifestyle. The Apache and Navajo, who lived in the southwest region, were initially hunters and gatherers. Over time, groups like the Navajo began to settle in villages, building domed houses called hogans, and cultivated crops such as maize, squash, and beans. To the north and east, in the Great Plains, indigenous communities also planted maize, squash, and beans, but were notable for hunting pronghorn and, extensively, bison, which was central to their diet and lifestyle. Bison provided not only meat but also raw materials for tools, weapons, shelters, and clothing.
