Cleaning the Environment

Question 1 How do micro-organism help in cleaning the environment?

Cleaning the Environment

Some micro-organism decompose the organic matter present in the dead plants, dead animals  and animal wastes, and convert them into simple substances which mix up with the soil.

Since micro-organism decompose the harmful and smelly dead remains of plants and animals and animal wastes into harmless materials, they clean the environment.

The micro-organism also help in recycling the nutrients (present in dead plants, dead animals and animal waste) in nature which can then be used as food by green plants.

If there were no micro-organism (decomposers)then the nutrients present in dead plants, dead animals and animal waste would never be released for use by new plants.
