Solution(By Examveda Team)

Bio-fertilizers are micro-organisms which bring about nutrient enrichment of soil by enhancing the availability of nutrients to crops. The micro-organisms which act as bio-fertilizers are bacteria, cyanobacteria (blue green algae) and mycorrhizal fungi. The symbiotic nitrogen-fixing bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.
