Multiple negative feedback mechanisms offer superior control over internal environment changes compared to a single mechanism, as they enable active adjustments in both directions to restore normality.
This card explains that multiple negative feedback mechanisms provide more control than a single mechanism because they allow for both active increase and decrease of levels to return to normal.
