Question

Quizplus · Accepted Answer

As habitat fragmentation increases, the size of patches decreases, leading to a larger proportion of the patch being exposed to the surrounding environment. This increases the edge effect, as conditions (e.g. temperature, humidity, wind) at the edges may be different from those in the patch interior. While options A and B are also factors that can contribute to edge effects, they do not directly answer why fragmentation increases the fraction of a patch subject to edge effects.
