Morphology
The phrase contrasts literal behaviours—'bark' (noisy threat) versus 'bite' (harmful action)—so the metaphorical meaning (talks threateningly but does not act) is fairly directly inferable from the constituents. However, it is a conventionalized metaphorical idiom that requires some cultural/figurative mapping and set-phrase knowledge, so it is not fully compositional for an uninstructed learner.
Etymology
The idiom all bark and no bite comes from the picture of a noisy dog that only barks and never bites. So it describes someone who 'threatens' or sounds dangerous but does not really 'hurt' anyone or 'act' on the threat.
