Question

A variety of microorganisms live in the human digestive tract, especially in the small intestine. Their actions aid in digestion, and they help synthesize essential vitamins. What best describes the relationship between a human and the intestinal microorganisms?

A. parasitic symbiosis, because the microorganisms live on food that the human provides
B. mutualistic symbiosis, because all of the species benefit from the relationship
C. predator/prey, because the microorganisms live on food that the human provides
D. decomposition, because the bacteria live on dead or decaying organic matter

Answer 1

Answer:

B

Explanation:

Answer 2

What best describes the relationship between a human and the intestinal microbes would be mutualistic symbiosis.

What is mutualistic symbiosis?

It is a form of obligate interaction between two organisms in which both of them benefit. Without the interaction, neither of them can survive.

The microbes in the intestinal tracks of humans aid food digestion. Without them, humans will have problems digesting certain foods.

In return, the human intestinal tracks provide a comfortable environment for the microbes to inhabit. In this environment, they are also provided with the necessary foods they need to survive.

Thus, it is a win-win situation for both organisms and a lose-lose if the relationship cuts.
