Explanation:

In the West, the term Old World is used to refer to Asia, Africa, and Europe. Generally, Old World refers to a part of the world that was known to its citizens before it came into contact with the Americans. On the other hand, the New World refers to the Americas and it is inclusive of North America, South America, and Central America. The Old World contrasts with the New World.

After the voyages of Christopher Columbus in 1492, the Columbian exchange brought New World crops such as maize, potatoes, sweet potatoes, and manioc to Europe, and Old World crops such as wheat, barley, rice, and turnips, and livestock including horses, cattle, sheep, and goats to the Americas.

The famous New World crops include rubber, tobacco, sunflower, cocoa, and cashew. Some plants such as cotton and yam as well as some animals like the dog are believed to have existed in both worlds.
