Which long-term consequence occurred because of decreased soil aeration in chinampa agriculture?

💡 Explanation

Decreased aeration in chinampas inhibits aerobic root respiration, limiting active transport of nutrients via ionic pumps; therefore crop nutrient uptake is reduced, rather than the other options involving gas production or decomposition rate changes because diffusion limits change.
