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.
