Is it true that microorganisms are not found in extreme environments?

Microorganisms are living organisms that are too small to be seen with the naked eye. They are single-celled or multi-celled organisms that include bacteria, viruses, fungi, protozoa, and algae.

Microorganisms are found in almost every environment on Earth, from the deep ocean to the soil and even inside other organisms. 

Microorganisms have been found in a wide variety of extreme environments, including hot springs, deep sea vents, acidic environments, and high salt environments, which prove that microorganisms can survive in extreme conditions.
