Which effect resulted from Aztec farmers intercropping maize with beans and squash in chinampa systems?

💡 Explanation

When intercropping maize with beans and squash, beans facilitate nitrogen fixation because their root nodules contain symbiotic bacteria, enriching the soil and benefiting neighboring crops. Therefore nitrogen fixation increases, rather than solely reducing wind, elevating carbohydrates, or solely reducing pest infestations, which depend on different mechanisms.
