xvi. Microbes in human welfare
Microorganisms or microbes are microscopic living organisms that cannot be seen with the naked eye. Because these can only be viewed under a microscope, they have been given the name microorganisms. Some microorganisms are single-celled, such as bacteria, algae, and protozoa, whereas others, such as many algae and fungi, are multicellular.
Microbes may exist in a wide range of settings, from icy cold to scorching hot, and from deserts to marshy areas. Microorganisms can be both dangerous and beneficial.
Some microbes are helpful and contribute to human well-being.
