Explanation:

Taxonomic Relationship of Eyelash Mites and Humans

The presence of eyelash mites in healthy humans highlights an interesting aspect of symbiotic relationships in nature. These tiny arachnids, scientifically known as Demodex mites, live in the follicles of human eyelashes and are generally harmless.

In terms of taxonomy, eyelash mites share the following hierarchical classifications with their human hosts:

  1. Kingdom: Both humans and Demodex mites belong to the Kingdom Animalia.
  2. Phylum: They are classified under the Phylum Arthropoda (for mites) and Chordata (for humans), indicating a difference at this level.
  3. Class: Eyelash mites belong to the class Arachnida, while humans are mammals, falling under the class Mammalia.

As such, the correct level of taxonomy where eyelash mites and their human hosts share a classification is the Kingdom, as they are both animals but belong to different phyla.
