Answer:
When the Italian explorer Christopher Columbus inadvertently discovered the Americas, it became known as the New World.
In a series of activities which were mostly commercial in nature for the benefit of Europe, crops (such as sugar, tobacco, chocolate, and potatoes), animals (such as horses), European culture, human populations (both slaves and colonial masters), technology, diseases, and new ways of doing things were exchanged between the "New World" and the "Old World"
In order to make for smooth colonial administration between the African leaders and the Colonial masters, African leaders were bribed with textiles, rum and manufactured goods from Europe.
Slaves were transported from Africa to the Americas to work on plantations of sugar , tobacco and cotton which were then transported to Europe.
This trade is what came to be referred to as the Columbian Exchange.
Europe is said to have benefited more from the Colombian Trade, as there has been a huge shift of resources to Europe , especially gold and silver from the New World and other regions.

One reason that some african americans were patriots was because a few of the high people during that time were racist. (This does not just go to african americans. White people were also patriots)
One reason that some african americans were loyalists was because some of the people that were in high power were actually african americans. These high powered african americans were not interfered with, due to there were many other people that bad guys wanted to turn into patriots. (DURING THIS TIME, very few african americans were in high power)
I hope that this helped! Please! Please! Please do not feel offended! I was only answering your question! And I caps locked "during this time" because this racist situation was only a big problem during the american revolution.
