Answer:

Unlike political borders, ecosystem boundaries are often dynamic and permeable.
This fluidity is due to the continuous exchange of matter and energy between adjacent systems, leading to transitional zones called ecotones where characteristics of both blending ecosystems can be observed.
Delineating these boundaries precisely is a significant challenge in ecological studies, as these zones are ecologically distinct and important in their own right.
