Answer:
The Aztecs used chinampas and terracing to grow food.
Step-by-step explanation:
A Chinampa is a garden that's surrounded by a body of water. They developed boats called "Chalupas" which allowed them to freely hop from garden to garden. It allowed them to freely grow crops without harming the environment. The other agricultural technique that the Aztecs used was terracing. Terracing is the process of shaping land for the purpose of more effective farming. By doing this, it provided them with more farmland.
