Step-by-step explanation:
The Hopi Indians were known for using 20 different varieties of corn and were from the Southwest region. The Hopi, along with other groups like the Zuni and Navajo, were agriculturalists who lived in permanent settlements and farmed crops including corn and squash. Their corn varieties were an important part of their diet and culture, with traditional farming practices adapted to the arid environment.
The Hopi people have a long-standing tradition of corn cultivation which is intertwined with their cultural practices and cuisine. They, like other Native American tribes in the region, skillfully adapted to the unique conditions of the Southwest and contributed to the rich agricultural heritage of the Americas.
