Morphology
The core meaning 'to chew one's fingernails' is directly and literally built from 'bite' + 'nail' with the possessive 'one's' indicating it is the speaker's own nails; the physical action is fully compositional. The common pragmatic extension that this behaviour signals anxiety is contextually inferable but not required for understanding the phrase, and the construction mirrors common reflexive actions in other languages, so it is transparent to a B1 learner who knows the constituents.
Etymology
The idiom bite one's nails comes from the simple, literal habit of people nervously bite the tips of their nails when they worry. So it now means 'to feel anxious' or 'nervous'.
