Options

A. Herbivorous
B. Carnivorous
C. Sanguivorous
D. Omnivorous.

Answer

**Step-by-Step Solution:**

1. **Understanding Amoeba**:
- Amoeba is a unicellular organism classified under the kingdom Protista, specifically as a protozoan. It is primarily found in aquatic environments.

2. **Identifying Nutritional Modes**:
- The question provides four options regarding the nutritional habits of amoeba:
- Herbivorous: Organisms that primarily consume plants.
- Carnivorous: Organisms that primarily consume animals.
- Sanguivorous: Organisms that consume blood (e.g., leeches).
- Omnivorous: Organisms that consume both plants and animals.

3. **Analyzing Amoeba's Diet**:
- Amoeba feeds on various microorganisms such as diatoms, dinoflagellates, and bacteria. Additionally, it can also consume aquatic plants.

4. **Determining the Correct Classification**:
- Since amoeba can consume both plant material (like algae) and animal material (like small microorganisms), it fits the description of an omnivorous organism.
- Therefore, it is not strictly herbivorous (only plants) or carnivorous (only animals), and it is certainly not sanguivorous (blood-sucking).

5. **Conclusion**:
- The correct answer to the question "Amoeba is" is **omnivorous** (Option D).
