How does nitrongen fixation help plants?

Nitrogen fixation is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3) or related compounds, making it accessible for plant uptake. This is crucial because nitrogen is an essential nutrient that plants need for synthesizing proteins, nucleic acids, and other vital compounds. Many plants, particularly legumes, form symbiotic relationships with nitrogen-fixing bacteria, enabling them to thrive in nitrogen-poor soils. By enriching the soil with usable nitrogen, nitrogen fixation enhances plant growth and productivity.
