If wetlands are destroyed, what effect will it have on migratory birds?

Correct answer: Resting and feeding sites may decrease

The direct answer is A: if wetlands are destroyed, migratory birds may lose important resting and feeding sites. Many migratory birds travel long distances between breeding and wintering areas. During the journey they need wetlands as stopover places where they can rest, find food, regain energy and sometimes avoid danger. Wetlands also provide water, plants, insects, fish and sheltered nesting or resting spaces. If these areas are drained, polluted or built over, available food and safe stopping places decrease. Option A correctly describes the likely effect. Option B is absurd because birds do not become mountains. Option C is wrong because destruction does not remove birds’ biological needs; they still need food, water and shelter. Option D is wrong because habitat loss does not make all birds domestic; domestication is a separate human-controlled process. The word “may” is appropriate because the exact impact depends on the extent and location of wetland loss. Memory cue: wetlands are migratory birds’ rest stops and food stations.
