Would the Colombian exchange benefit or be a problem for the amercias

You can argue both ways, but here are a few reasons for each:

Benefit:

Introduced foreign crops and animals that hadn't been previously existing Sparked an economy and trading routes between Europe and the Americas Because of the introduction of cash crops to the Americans, the American agricultural industry was becoming a big part of the economy

Became a detriment:

Alongside the crops and animals being brought over, many diseases traveled and made their way into America, killing a generous amount of people Malaria was one of the major diseases brought over The Colombian Exchange was also bringing settlers into the Americas which pushed out the preexisting Native settlers; this led to many major conflicts down the road
