Which outcome occurs when nitrogen fixation is limited within estuarine sediments?

💡 Explanation

When nitrogen fixation is limited, bioavailable nitrogen decreases because nitrogenase, the enzyme complex carrying out biological nitrogen fixation, requires molybdenum, which is often rate limiting in estuaries; therefore, shellfish growth decreases, rather than increased eutrophication which needs nitrogen richness.
