Final answer:
The urban population growth of Teotihuacan due to environmental methods is closely related to the Aztecs, who developed advanced urban planning and agricultural techniques to control their environment.
Step-by-step explanation:
The rapid growth in urban population at Teotihuacan due to environmental control methods is most comparable to the techniques used by the Aztecs. The Teotihuacan civilization was known for its extensive trade networks and its control over resources such as obsidian. Like Teotihuacan, the Aztecs, who later controlled central Mexico, created an impressive city known as Tenochtitlán. It was a hub of commerce, religion, and society, estimated to have a population of around 100,000 people, and known for its advanced agricultural techniques and urban development. Both civilizations were also proactive in their environmental control methods, with Teotihuacan managing the trade of resources, and the Aztecs enhancing their agriculture and city planning to accommodate a dense urban population.
