Answer – A
- Nitrogen fixation is a chemical process by which molecular nitrogen (N2), with a strong triple covalent bond, in the air is converted into ammonia (NH3) or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. Rhizobium is a rod-shaped nitrogen-fixing bacteria live symbiotically within the roots of several leguminous plants such as alfalfa, sweet clover, sweet pea, lentils etc.
- The amaranth plant is a grain and green crop plant, because it is not a pulse crop and do not nitrogen-fixing mechanism. The purslane plant is one of the few vegetables that are rich in omega-3 fatty acids, which are important to support healthy arteries and can help prevent strokes, heart attacks, and other forms of heart disease. It also does not have a nitrogen-fixing mechanism at the root zone.
