← ScienceWhich outcome occurs when atmospheric nitrogen fixation exceeds plant uptake capacity?
A)Eutrophication increases in nearby waterways✓
B)Soil salinity decreases dramatically
C)Plant respiration experiences significant increases
D)Methanogenesis subsequently reduces soil nitrogen
💡 Explanation
Eutrophication occurs because increased fixed nitrogen from Haber-Bosch process runoff overwhelms plant capacity, leading excess nitrogen. This triggers algal blooms, rather than altering respiration or methanogenesis; therefore the waterways become oxygen depleted.
