Explanation:

Microorganisms are small living beings whose dimensions do not allow them to be observed with the naked eye by man. Thus, they can only be viewed under the microscope. Many microorganisms live in soil and fallen leaves on the forest floor. In general, microorganisms contribute to soil fertilization, substance recycling and participate in biogeochemical cycles. They can still be used in the manufacture of products such as yogurt, wines, cheese, vinegars and breads.
