Quizplus · Accepted Answer

The mallard ducks eat floating plants and small organisms at or near the surface, which suggests that they are most likely found in the littoral zone (near the shore) or the limnetic zone (open water surface). Therefore, any change to the littoral or limnetic zones would have the greatest impact on their food sources and ultimately, their survival.
