There isn't a single, universally accepted name for the human body as an ecosystem. However, some common terms used to describe it include:

* Human microbiome: This term focuses on the vast community of microorganisms (mainly bacteria) that live in and on our bodies. It's often used interchangeably with "human microbiota."

* Human holobiont: This term highlights the interdependence between humans and their associated microbes, emphasizing that they function as a single biological unit.

* Human-associated microbial ecosystem: This term emphasizes the ecological aspect of the interactions between humans and their microbes.

Ultimately, the best term to use depends on the context and the specific focus of your discussion.
