Answer

To answer the question "Amoeba can digest," we will analyze the digestion process in amoeba and the types of substances it can break down.

### Step-by-Step Solution:

1. **Understanding Amoeba's Digestion Method**:
- Amoeba performs intracellular digestion. This means that the digestion occurs within the cell itself, rather than in a digestive cavity.

2. **Mechanism of Food Intake**:
- Amoeba uses extensions of its cell membrane called pseudopodia to engulf food particles. This process is known as phagocytosis.

3. **Types of Substances Amoeba Can Digest**:
- Amoeba can digest various types of organic materials, including:
- **Proteins**: These are broken down into amino acids.
- **Starch**: This carbohydrate is digested into simpler sugars.
- **Fats**: These are broken down into fatty acids and glycerol.
- Additionally, amoeba can also digest cellulose and sugars.

4. **Evaluating the Options**:
- The options provided are:
1. Protein
2. Protein only
3. Starch and fat only
4. Protein and fat only
- Since amoeba can digest proteins, starch, and fats, the correct answer must encompass all three.

5. **Conclusion**:
- Therefore, the correct answer is that amoeba can digest proteins, starch, and fats.

### Final Answer:
Amoeba can digest **protein, starch, and fat**.
