 This shot shows how, in the deep shadows of an image, both dynamic range (black-to-red-to-yellow banding) and noise become an issue.

1) By increasing the shutter time at a constant ISO, both noise and dynamic range are improved.

2) By increasing ISO, dynamic range is improved (no banding), but noise is still a problem.

The relative amounts of noise in the shots cannot be compared, but the point is: increasing ISO boosts levels AND noise. Increasing shutter boosts levels without noise.
