A major rise in algae will degrade water quality, reduce habitats and food supplies, and reduce the oxygen required for fish and other aquatic species to thrive. What two agriculture nutrients cause the greatest problems in surface waters that lead to algae growth and depleted O₂

• Oxygen and nitrogen

• Nitrogen and phosphorus

• Hydrogen and nitrogen

• Helium and phosphorus
