An argument concerning the impact of urban noise on bird populations can be constructed from the five statements below. Arrange the statements in their logical order to form a continuous reasoning chain. Begin with the foundational empirical observations, progress through the intermediate inference, introduce the general ecological principle, and end with the argument's ultimate main conclusion.
- 1Field biologists have recently documented that urban noise pollution forces several songbird species to sing at much higher frequencies.
- 2Producing these higher-frequency vocalizations requires songbirds to expend significantly more metabolic energy than they do in quieter environments.
- 3This increased energy expenditure forces the songbirds to allocate less energy to other essential survival activities, such as foraging.
- 4Any environmental factor that reduces the energy a species can allocate to foraging will inevitably suppress its overall population growth.
- 5The continued escalation of urban noise pollution will ultimately lead to a decline in the population density of these songbird species.
Answer
The correct logical sequence begins with the two empirical observations about vocalizations and energy, followed by the intermediate conclusion about foraging, the general ecological principle, and ends with the ultimate conclusion about population decline.
The argument structurally flows from direct observations to a final predictive claim. First, the facts about urban noise and energy expenditure are established. These combine to support the intermediate conclusion that birds have less energy for foraging. The general ecological principle is then introduced to connect this reduction in foraging energy to the ultimate main conclusion: a decline in population density.
