Which effect results when increased phosphorus limits nitrogen fixation in oceans?

💡 Explanation

Limited phosphorus reduces ATP production needed for nitrogenase enzyme activity during nitrogen fixation; therefore, cyanobacteria photosynthesis decreases because of insufficient fixed nitrogen availability, rather than increased diatom growth or carbon sequestration.
