What effect of the columbian exchange does this image illustrate?

The Exchange was of species and crops between New World and Old World. This had many effects some positive and some negative on both Worlds.

A positive effect was that new crops and species were introduced to both while there were some diseases brought to Native Americans which they had no immunity against resulting in fatalities. Another negative effect was the removal of Native Americans for the economic needs of Europeans leading to death of many.
