Question

Good afternoon, I am struggling with this question may someone help me figure it out?

"It is said that the microbiota of a human represents 2% of its mass. Explain how this number was found. Compare the average number of cells."

Answer 1

There are trillions of microorganisms in the human body. That number is more than 1 in 10. However, because of their small size, microbes only make up about 1-3% of body mass, but they play an important role in human health.
