American Indian groups met their basic needs of food, clothing, and shelter based on the natural resources available in their local geography and climate. They used natural resources like fishing in rivers, hunting animals, and growing crops to obtain food. Their clothing was made from animal skins and plants from the local environment. Their shelters utilized materials found nearby such as sod, stones, wood, and animal skins. The tribes relied on natural resources for food, human resources like hunters and farmers, and capital resources including canoes, bows, and spears.
