Write notes about the fixation of aerial nitrogen.
Nitrogen fixation is the process of converting atmospheric nitrogen into usable forms for plants and organisms. Certain bacteria can take in atmospheric nitrogen and convert it into ammonia. Aerial nitrogen fixation occurs when bacteria live on the surfaces of leaves, taking in nitrogen and fixing it into a form that can be used by the plant. This process is important in areas with poor soil. Legumes and other plants can host nitrogen-fixing bacteria.
