Systems Analogy
A sprawling internal ecosystem of specialized biological workers processing raw harvests into essential regional nutrients.
The collective community of microorganisms (bacteria, fungi, archaea, and viruses) residing within a specific ecological niche, such as the human gastrointestinal tract. Note: While 'microbiota' refers to the physical population of microbes and 'microbiome' refers to their collective genomes and habitat, they are functionally used interchangeably in clinical literature.
