Answer:
The Plains Indians were hunters and agriculturalists, they hunted large animals like bison and planted crops such as beans, squash, and corn. Due to being dependent upon hunting, the Plains Indians were nomadic and would easily set up their teepee housing units wherever they went. Several tribes would perform the Sun Dance which is a ritual of sacrifice for the benefit of the community. As the horse was introduced to the tribes that helped in hunting and movement, it would begin to create competition among the different tribes.
