Which factor most directly supports banana slug survival in a forest ecosystem?

• A. Bark thickness on trees
• B. Sunlit, exposed soil
• C. Microhabitat moisture and abundant leaf litter
• D. High wind exposure

Answer: (C)

Banana slugs stay hydrated by living in a damp, shaded microhabitat on the forest floor. Their skin is permeable and dries out easily, so they rely on moisture to move, feed, and reproduce. Leaf litter provides that moisture by retaining humidity and creating a cool, protected space under decaying matter and leaves. It also hosts fungi and detritus they feed on, and offers hiding spots from predators. Bark thickness isn’t directly about keeping the slug moist on the ground, sunlit soil dries out quickly, and high winds increase drying and can expose or dislodge slugs. So the moist, leaf-litter–rich microhabitat best supports their survival.
