Question

Quizplus · Accepted Answer

Absorption of nutrients through the body surface is an adaptation found in flatworms that are parasitic. This adaptation allows them to absorb nutrients directly from their host's tissues. Flatworms that are not parasitic have a highly branched gastrovascular cavity for digestion and use simple diffusion for nutrient absorption. Large size and an oxygen transport system are not adaptations specifically associated with flatworms' parasitic lifestyle.
