HORTICULTURE

Detailed explanation-1: -Introduced staple food crops, such as wheat, rice, rye, and barley, also prospered in the Americas. Some of these grains-rye, for example-grew well in climates too cold for corn, so the new crops helped to expand the spatial footprint of farming in both North and South America.

Detailed explanation-2: -The exchange introduced a wide range of new calorically rich staple crops to the Old World-namely potatoes, sweet potatoes, maize, and cassava. The primary benefit of the New World staples was that they could be grown in Old World climates that were unsuitable for the cultivation of Old World staples.

Detailed explanation-3: -The Columbian Exchange connected almost all of the world through new networks of trade and exchange. The inter-continental transfer of plants, animals, knowledge, and technology changed the world, as communities interacted with completely new species, tools, and ideas.
