Answer:
Some Native American groups were nomadic in order to follow the migration of the animals they hunted for food.
Step-by-step explanation:
Although there were a great variety of different settlement patterns among the indigenous Native Americans who lived in what is today North America when the Europeans arrived, there were some groups that were nomadic or semi-nomadic. They would displace themselves at certain times of the year to follow the migration of the animals they hunted for game like Bison or because of changes to the seasons. The Plains Indians like the Lakota and Blackfoot are most famous for their nomadic lifestyle that increased as they gained access to horses from the 17th century through the late 19th century. As groups developed horticulture and agriculture it made them settle at least semi-permanently into villages like the Pawnee.
