siniylev [52]

Answer:

Some of the goods that are native to the Americas but were introduced in Europe are tobacco, tomatoes, potatoes, corn, Jerusalem artichokes...

Explanation:

The Americas were two continents that were not in touch with the rest of the world. This led to a situation where these two continents had an abundance of goods that were not known to people living outside of them. When the Europeans reached the Americas, among other things, they encountered a lot of these goods and immediately saw their potential.

Through the Columbian exchange, goods like tobacco, tomatoes, potatoes, corn, Jerusalem artichokes, all found their way toward Europe. Tobacco soon became the most used recreational plant The tomatoes, potatoes, and corn became integral parts of the European diet and helped massively in the elemination of famine. The Jerusalem artichoke was used by both humans and animals, as it was very easy to grow and highly productive.
