Answer:
A person gets diseases because different microorganisms attack him/her. These harmful microorganisms are bacteria, virus, fungi and protozoa. They are the tiniest creatures on earth. They can't be seen through naked eyes. We can only see them under a microscope which make things look 1000 times bigger. microorganisms are in air, water, ground, items and and outside of living and non-living things. When they go inside our body, we have to face illness and disease.
