Options

A. It is parasite
B. It lives in intestine
C. It does not need food
D. It absorbs its food from general body surface

Answer

### Step-by-Step Solution:

1. **Understanding the Organism**:
- Tapeworms belong to the phylum Platyhelminthes, which are flatworms. They are characterized by their flat, ribbon-like bodies.

2. **Absence of Digestive System**:
- Tapeworms do not possess a digestive system. This means they lack specialized organs such as a mouth, stomach, or intestines to process food.

3. **Nutrient Absorption**:
- Instead of digesting food, tapeworms absorb nutrients directly through their body surface. This is possible because their body is covered with a tegument, which allows for the absorption of nutrients from the host's digestive system.

4. **Method of Nutrient Uptake**:
- The process through which tapeworms absorb nutrients is called diffusion. They rely on simple diffusion to take in necessary substances like nutrients and oxygen directly from their environment.

5. **Conclusion**:
- Therefore, the reason tapeworms do not have a digestive system is that they absorb nutrients directly from the host's body through their skin, making a digestive system unnecessary.
