Which ecological consequence arises when specific soil bacteria decline?

💡 Explanation

When soil bacteria die, there is a decline in nitrogen fixation. Atmospheric inputs reduce because the bacteria that convert gaseous nitrogen into usable forms are diminished; therefore, less nitrogen becomes biologically available, rather than any change in other elemental cycles under alternative deficiencies.
