3. Nitrogen-fixing bacteria live in protective nodules (bumps) on the roots of some plants.
These bacteria are able to convert gaseous nitrogen from the air into a form of nitrogen
that the plants can use. Which type of relationship is this?
~mutualism***
~predation
~commensalism
~parasitism

I think the answer is mutualism but I'm not sure if they'd count the Nitrogen-fixing bacteria would benefit from the process or not. Please, help me

I am no biologist but suspect you are right. Obviously the plant benefits from the N2 but I do not think the bacteria would be there unless they gained something (like a home). The other choices make no sense.
