primary source secondary source
a map from 2024 showing which foods, animals, and diseases were exchanged
a documentary about the impacts of the columbian exchange, from 2013
a book from 1972 about the biological and cultural impacts of the columbian exchange
a european cookbook from the 1500s that uses ingredients from the americas, such as corn

Explanation:

A primary source is from the time - period of the event or a direct participant. A secondary source interprets or analyzes primary sources. The 2024 map, 2013 documentary, and 1972 book are interpretations made long after the Columbian Exchange, so they are secondary sources. The 1500s cookbook using new - world ingredients is from the time of the exchange and is a primary source.

Answer:

a map from 2024 showing which foods, animals, and diseases were exchanged: Secondary source
a documentary about the impacts of the Columbian Exchange, from 2013: Secondary source
a book from 1972 about the biological and cultural impacts of the Columbian Exchange: Secondary source
