Final answer:
The Athapascan tribes, with the Navajo as sedentary farmers and the Apache as nomadic hunters and gatherers, had lifestyles adapted to the Southwest's resources and geography.
Step-by-step explanation:
The Athapascan tribes, which include the Apache and Navajo, had different ways of life. The Navajo were among the indigenous peoples who became sedentary farmers, cultivating crops such as corn and squash, and building permanent settlements with structures like multistory pueblos and ceremonial centers. In contrast, the Apache were primarily nomadic hunters and gatherers. They moved around the region engaging in hunting and also raided the crops of neighboring sedentary groups at times. The differing lifestyles among the Athapascan tribes were adapted to the availability of resources and the geographical features of the Southwest.
