Q1
Two students draw models of how road construction through a wetland affects biodiversity.
Model 1: Road construction → Wetland drained/filled → Loss of breeding sites → Amphibian populations decline → Reduced wetland biodiversity
Model 2: Road construction → Cars drive faster → More noise → Road gets wider → Reduced biodiversity
Which model more completely represents an impact pathway from a human activity to a biodiversity outcome, and why?
