During the Columbian exchange, food, plants, animals, ideas and communicable diseases were exchanged between the New World and the Old World.

Explanation:

The Columbian Exchange was the exchange of foods, plants, animals, ideas and communicable diseases between the New World (Americas) and the Old World (Europe) that occurred after 1492, which is after Columbus’ first voyage towards India.

Christopher Columbus brought to the Americas horses, goats, sugar plants and diseases like smallpox, influenza, typhus, and measles.

Columbus brought to Europe many things like tobacco, chocolate, corn, tomatoes, and potatoes.

Although Columbian Exchange had many advantages, as introducing new types of food, plants, and animals, it also had a lot of negative consequences when it comes to indigenous people of the Americas.

Besides the diseases that devastated Native Americans, Europeans also introduced slavery. The Columbian Exchange caused a drastic labor shortage in the Americas, so Europeans used African slaves as a labor force in the New World. They worked on plantations to grow crops or another difficult task, which eventually stimulated European colonialism in Africa.
