Which outcome can arise when excessive freshwater melt influences upwelling?

💡 Explanation

Freshwater influx reduces density, preventing the mixing necessary for upwelling; this nutrient stratification inhibits the delivery of vital nutrients to the surface because density differences prevent vertical mixing, affecting primary productivity rather than other marine processes.
