Which risk increased for pre-Columbian societies during periods of volcanic ashfall interrupting chinampa agriculture?

💡 Explanation

Falling volcanic erupta disrupts photosynthesis cycle because light attenuation reduces solar input, inhibiting the Maize growth and crop yields due to reduced rates of carbon dioxide assimilation. Therefore, less maize will be produced, rather than altering water tables or canal silt composition.
