Why did many native american tribes stop farming after the colombian exchange? What plants did europeans bring to the americas?(2)

Several Native American groups left farming to become buffalo-hunting nomads, also the population dropped very low due to diseases being brought. They brought barley and rye. They brought wheat, which was originally from the Middle East . They brought plants that had originally come from Asia, including sugar, bananas, yams, citrus fruit, coffee, rice, and sugarcane.

Explanation:

The Columbian exchange of crops affected both the Old World and the New. More importantly, they were stripping and burning forests, exposing the native minor flora to direct sunlight and to the hooves and teeth of Old World livestock. The native flora could not tolerate the stress.Explorers and conquistadors brought many new plants to the Americas and also They brought European crops such as barley and rye. They brought wheat, which was originally from the Middle East . They brought plants that had originally come from Asia, including sugar, bananas, yams, citrus fruit, coffee, rice, and sugarcane. Also Europeans carried a hidden enemy to the Indians: new diseases. Native peoples of America had no immunity to the diseases that European explorers and colonists brought with them. Diseases such as smallpox, influenza, measles, and even chicken pox proved deadly to American Indians.
