Meter and structure in poetry are used to create the ambiance, environment and tone of a poem. They create the images in readers mind as envisioned by the poet so that readers can relate to the poet's ideas and share the emotions. In short, meter and structure are very important in conveying the themes and ideas of a poem.
In the Romantic era, poets tried to make structural organization of the poem look effortless when in fact the structure was the results of lot of hard works. The meter created the desired rhythm that was in sync with the theme. In case of Lord Byron, he used for example iambic rhythm in song “She Walks in Beauty” to achieve effortless tone as the beauty of the lady was effortless and graceful. Apart from love poems, he also used meter to create the sensation of wild passion, disorder and chaos. Those were also characteristic of the Romantic era.
Byron's use of meter and structure doesn't fully represent the ideas of the romantic movement. Although he did write about themes that were considered romantic, his meter and structure weren't very different from the poets that came before him.
I think this because this sentence is only the sentence that goes along with the passage. The passage talks about the features of the penguin, not anything else about it.
