Microorganisms such as bacteria and fungi play an important role in maintaining the soil fertility. Microbial action on dead organic matter releases nutrients in the soil thus raising the fertility status of the soil.

Answer 2

Answer:

nitrogen fixing bacteria convert nitrogen in the air to nitrates in the soil, which plants use for making proteins

decomposing bacteria convert nitrogen-containing compounds dead or waste organic matter into ammonia

nitrifying bacteria convert the ammonia into nitrates

these increase soil fertility

decomposing bacteria also effectively remove dead organisms and wastes, cleaning the environment
