Rhizobia are bacteria that fix nitrogen from the atmosphere. They live in the roots of many legume plants, forming structures called nodules. The plants use the fixed nitrogen, and the bacteria consume metabolites from the plants. This interaction is an example of parasitism. mutualism. commensalism. neutralism.
