Which is not component of nutrition in Amoeba

Options

A. Phagocytosis
B. Intracellular digestion
C. Saprotrophy
D. Exocytosis.

Answer

To determine which option is not a component of nutrition in Amoeba, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Amoeba's Nutrition**:
- Amoeba is a unicellular eukaryote that primarily feeds on smaller organisms. It uses a method called phagocytosis to capture and ingest its prey.

2. **Analyzing the Options**:
- **Option A: Phagocytosis**:
- This is the process by which Amoeba captures and engulfs its prey. It is a key component of its nutrition. Therefore, this option is not the answer.

- **Option B: Intracellular Digestion**:
- After capturing food, Amoeba digests it inside its cell. This process is known as intracellular digestion, which is also a part of its nutritional process. Thus, this option is not the answer.

- **Option C: Saprotrophy**:
- Saprotrophy refers to the mode of nutrition where organisms feed on dead and decaying organic matter. Amoeba does not utilize this method for nutrition, making this the correct answer to the question.

- **Option D: Exocytosis**:
- Exocytosis is a process that allows Amoeba to expel waste and absorb nutrients. This process is involved in its nutrition, so this option is also not the answer.

3. **Conclusion**:
- The option that is not a component of nutrition in Amoeba is **C: Saprotrophy**.

### Final Answer:
**C: Saprotrophy**
