Which of the following is NOT a true statement about soil microorganisms? A. Microorganisms can be used for medicinal purposes. B. Microorganisms can use oxygen, sulfur, iron or nitrogen to respire. C. Microorganisms can cause disease in plants, animals and humans. D. Microorganisms cannot decompose organic matter.

Answer 1

Microorganisms can be used for medicinal purposes, respire with different elements, cause disease, and decompose organic matter.

Step-by-step explanation:

Microorganisms can be used for medicinal purposes, such as producing antibiotics and vaccines, so it is a true statement. Microorganisms can use oxygen, sulfur, iron, or nitrogen to respire, which is another true statement. Microorganisms can also cause disease in plants, animals, and humans, so this statement is true. However, the statement D, which says that microorganisms cannot decompose organic matter, is not true. Microorganisms, such as bacteria and fungi, play a crucial role in decomposing organic matter and recycling nutrients in ecosystems.
