Which outcome occurred when pre-Columbian chinampas lacked sufficient drainage during prolonged rainfall events?

💡 Explanation

When chinampas experience prolonged rainfall and insufficient drainage, waterlogging promotes anaerobic soil conditions because microbes deplete oxygen as they decompose organic matter. Therefore anaerobic conditions harm crops, rather than the alternatives, which require aerobic rich soil or nutrient flow.
