The question is incomplete. The complete question is as follows:

What are the disadvantages of a flatworm's digestive system having only one opening?

Answer:

The digestive system of the flatworms has been modified depending on their host parasite interaction. They have simple digestive system with the single opening.

This digestive system might have some disadvantages as the food consumption is not continuous due to the single opening. The ingestion and excretion as same opening and this increases the timing of the digestion and excretion process. The energy is expanded more in this type of the digestive system.

Answer:

The correct answer is - cannot consume food continuously.
