Explanation:
The second line of the poem 'In a Station of the Metro' by Ezra Pound communicates the temporary nature of life through the imagery of 'Petals on a wet, black bough.' The use of petals, delicate and ephemeral by nature, on a wet, black bough suggests a fleeting moment, mirroring the transient nature of life itself. This comparison evokes the idea that life, like the petals that eventually wither and fall, is transient and impermanent.
