Question

the human microbiome consists of over 100 trillion ________ which help us stay healthy. options: skin cells, consumers, microorganisms, blood cells

Explanation:

The human microbiome is defined as the collection of microorganisms (like bacteria, fungi, viruses) that live in and on the human body. Skin cells and blood cells are human body cells, not part of the microbiome. "Consumers" is a general ecological term not specific to the microbiome. So the correct term is microorganisms.

Answer:

C. microorganisms
