Final answer:
The map illustrates the Columbian exchange of plants and animals between Europe and the Americas, which had a significant impact on ecosystems, cultures, and economies.
Step-by-step explanation:
The map illustrates the Columbian exchange of plants and animals between Europe and the Americas. This was the transfer of crops, animals, diseases, and technology that took place after Christopher Columbus's voyage in 1492. The exchange had a significant impact on the ecosystems, cultures, and economies of both regions.
European animals thrived in the Americas, while American crops like maize and potatoes had a major influence on European diets and population growth. However, the exchange also led to the accidental transfer of diseases, causing the deaths of a large portion of the Native American population.
