What is the difference between second order zero bode plot and second order pole bode plot?

A Bode plot is usually of the system, so embraces the overall effect of poles and zeros combined.

A bandpass response has a second-order in both numerator and denominator, so I suppose you could plot these separately out of curiosity. I'd expect to find both numerator and denominator will be underdamped second-order systems, but their corner frequencies will differ.
