Explanation:

The Columbian Exchange was the transfer of a large number of plants and animals, technology and cultural achievements, as well as population groups (including the forced relocation of slaves) from the Old World to the New World and vice versa as a result of the discovery of America by Christopher Columbus in 1492. Exchange has also led to the spread of disease.

Many animals and plants came to another continent, such as rats from Europe, and Colorado beetles from America. Among the transferred plants there were many weeds, such as tobacco, cocaine bush, hops, hodgepodge, wild oats and kudzu, and a number of parasitic fungi.Explanation:
