Which outcome results when highland maize is cultivated above its optimal thermal limit in a pre-Columbian environment?

💡 Explanation

Lowered photosynthetic efficiency arises in maize because metabolic processes slow due to decreased temperatures, caused by climbing above optimal temperature limits; therefore energy production declines, rather than rising resistance to pathogens or improved nitrogen fixation rate.
