Microorganisms can be defined as the organisms which are seen with the aid of microscope. This category includes the bacteria, algae, fungi, protozoa and viruses. These microorganisms play an important role in the decomposition of the biological materials. The nutrients are also recycled by these microorganisms. the microorganisms bound in a soil serve this purpose. Moreover, the microorganisms, such as algae carry out the process of photosynthesis and make their own food.
