B)bacteria on the roots of legumes

D)the Haber process
E)the Ostwald process

Question

Quizplus · Accepted Answer

The Ostwald process is used for producing nitric acid from ammonia, but it does not contribute to nitrogen fixation. Nitrogen fixation refers to the conversion of atmospheric nitrogen (N2) into a form that is usable by living organisms, such as ammonia (NH3). Lightning, bacteria on the roots of legumes, the combustion process in car engines, and the Haber process all contribute to nitrogen fixation by converting atmospheric nitrogen into compounds usable by plants and other organisms. The Ostwald process, however, is concerned with the conversion of ammonia into nitric acid and does not involve the fixation of atmospheric nitrogen.
