Digestion in Hydra takes place within

Options

A. pelvic cavity
B. Abdominal
C. Gastrovascular cavity
D. Pericardial cavity

Answer

**Step-by-Step Solution:**

1. **Understanding Hydra**: Hydra is a genus of small, simple freshwater animals known for their radial symmetry. They are commonly found in aquatic environments.

2. **Feeding Mechanism**: Hydra captures its prey using tiny stinging cells located on its tentacles. These tentacles help in grasping small aquatic animals.

3. **Digestion Process**: Once the food is captured and enters the mouth of the Hydra, the digestion process begins.

4. **Types of Digestion**: In Hydra, both extracellular digestion (where enzymes break down food outside of cells) and intracellular digestion (where food particles are engulfed by cells) occur.

5. **Location of Digestion**: The digestion in Hydra takes place within the gastrovascular cavity, which serves as both a digestive and circulatory system.

6. **Eliminating Incorrect Options**:
- Pelvic cavity: Not applicable to Hydra.
- Abdominal cavity: Not applicable to Hydra.
- Pericardial cavity: Not applicable to Hydra.
- Therefore, the only correct option is the gastrovascular cavity.

7. **Conclusion**: The correct answer to the question is that digestion in Hydra takes place within the gastrovascular cavity.

**Final Answer**: Digestion in Hydra takes place within the gastrovascular cavity.
