Write a short paragraph on the harms caused by microorganisms.

We all know that microorganisms are present everywhere.  Let us read more about them.

What are microorganisms?

Microorganisms are minute organisms that are invisible to the naked eye. Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc.

Harmful effects

These microbes can be beneficial as well as harmful in many ways, which are listed below.

Food spoilage

Some micro-organisms such as fungus spoil our food. For example, when left unused under moist conditions, bread gets spoilt by fungus, producing a white cotton-like growth on the bread. This leads to food poisoning.

Spreading of diseases

Microorganisms cause diseases in animals. For example, in humans, bacteria cause diseases such as tuberculosis, cholera, typhoid, etc.

Disinfecting the surfaces where the microbe resides

It spreads the harmful and poisonous substance where it resides. For example, if it resides in a dirty place like stagnant water and then carries the dirt and resides on food that is kept open.
