What is the geographical constraint imposed by the zebra's frequent need to drink water?

Answer

Their feeding grounds must be closely tied to reliable water sources

A fundamental constraint on zebra feeding ecology is their regular requirement for hydration; they generally need to drink water every single day. Unlike certain desert-adapted herbivores capable of going long periods without drinking, this daily necessity geographically ties the zebra's feeding grounds to accessible water sources such as rivers, springs, or waterholes. This dependency imposes a limit on how far they can wander while foraging, meaning the composition of the grass they consume is inherently dictated by what grows near these reliable liquid resources, whether that grass is high quality or dry.
