Question

Quizplus · Accepted Answer

Nitrogen fixation is primarily accomplished by certain types of bacteria, such as Rhizobium and Azotobacter. Legumes (such as soybeans and peas) have a symbiotic relationship with these bacteria, allowing them to convert atmospheric nitrogen into a form that can be used by the plant. Algae and protozoa do play a role in nutrient cycling, but do not fix nitrogen. Round worms have no involvement in nitrogen fixation.
