    Solution

    Azolla is a genus of aquatic ferns that can be grown in rice fields. It is often used as a biofertilizer in rice cultivation. Azolla has a symbiotic relationship with nitrogen-fixing cyanobacteria, which allows it to capture and fix atmospheric nitrogen, enriching the soil with this essential nutrient.
