How do microorganisms help to clean the environment?

Microorganisms clean the environment by breaking down waste, recycling nutrients, and removing harmful pollutants from soil, water, and air. They act as natural decomposers and play an important role in maintaining ecological balance.

Microbes such as bacteria and fungi decompose dead plants, animals, and organic waste into simpler substances, which enrich the soil and return nutrients to nature. In sewage treatment plants, microorganisms digest organic matter in wastewater and help produce clean water.

Some bacteria are also used in bioremediation, where they break down harmful substances like oil spills, plastics, and toxic chemicals into harmless products. This prevents pollution and protects the environment.

In addition, microorganisms recycle nitrogen, carbon, and other elements through natural cycles, ensuring the continuous availability of essential nutrients for plants and animals.
