Question 10 (1 point)
Which of the following is LEAST likely to be a pathogen
A) A bacterium found in a cow’s digestive system
B) A virus found in birds
C) An archaean from a hot spring in Yellowstone National Park
D) A fungus found growing on bread

Did you know that many organisms that seem harmless or even beneficial can be misunderstood? For instance, while bacteria in a cow’s digestive system play crucial roles in digestion, they’re not harmful; they’re actually helpful in breaking down tough plant materials!

On the other hand, while certain fungi can spoil our bread, like the mold we often see, many types of fungi are vital in ecosystems as decomposers or are used in delicious delicacies like mushrooms. So, the world of microbes is filled with surprises!
