Which irrigation-related consequence arose when Tenochtitlan's *chinampas* exceeded optimal density?

💡 Explanation

Decreased spacing caused `nutrient competition` because the soil fertility was finite; therefore maize yields declined, rather than excess moisture, because humidity changes or waterborne vectors are less direct yield limiters than nutrient limitation.
