Which of the following is NOT a type of potentially harmful organism?

Carbohydrates are not classified as potentially harmful organisms. Instead, they are organic compounds that serve as a major source of energy and are essential for various biological functions in both humans and other organisms. They are commonly found in foods such as grains, fruits, and vegetables. Unlike bacteria, viruses, and fungi, carbohydrates do not possess the characteristics of living organisms and do not cause infections or diseases.

Bacteria, viruses, and fungi, on the other hand, are all types of microorganisms that can lead to harmful effects on health. Bacteria can cause infections and are involved in various diseases. Viruses are even smaller entities that require host cells to replicate and can lead to various illnesses. Fungi can also be pathogenic, leading to conditions such as athlete’s foot or yeast infections. This understanding clarifies why carbohydrates do not fit into the category of harmful organisms, while the other three options do.
