Question

Researchers argue that some bacteria found in the human gut are in a symbiotic relationship with humans, called mutualism. Which of the following observations is consistent with this argument?

Answer 1

Answer:

Bacteria provides vitamins to humans

Explanation:

The correct answer would be that bacteria provides vitamins to humans.

By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.

Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.

Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.
