Aerial metagenomics best refers to which one of the following situations?
Correct Answer A. Collecting DNA samples from air in a habitat at one go

Aerial metagenomics refers to filtering environmental air through specialized sampling membranes to capture and sequence airborne environmental DNA (eDNA).
This enables simultaneous surveillance of biological taxa—including mammals, birds, vegetation, fungi, and airborne microbes—present within an ecosystem without requiring direct contact or visual observation.
