2) overseas expansion and conflict

3) growth of trade markets

A way in which the European economy was impacted by the Columbian Exchange was that new crops were introduced in Europe and food production increased.

Explanation:

The Columbian Exchange was the enormous spread and interaction of agricultural goods and products from flora and fauna, which were initially novel for the respective continents between the eastern and western hemisphere. It appeared as one of the repercussions of European expansion after Christopher Columbus' discovery of America in 1492 and contributed to an ecological change on both sides of the Atlantic, particularly in the natural history of Europe and America from the 16th century.

The exchange of plants and animals transformed the European, American, African and Asian ways of life. Food that some peoples had never seen before became indispensable. Virtually no society on earth could avoid the effects: for example, potatoes were unknown outside of South America before 1492, but were indispensable in Ireland in the 18th century. The first European import, the horse, changed the habits of many Native Americans on the prairies to a nomadic lifestyle of hunting bison on horseback. The tomato sauce, made from New World tomatoes, became an Italian trademark, but coffee and sugar cane from Asia were the most important crops in Latin America. Before there were no oranges in Florida, no bananas in Ecuador, no cattle and dairy products in Argentina, no rubber trees in Africa, no livestock farming in Texas and no chocolate in Switzerland.
