Heterotrophic ingestive nutrition is found in

Options

A. Monera
B. Animalia
C. Plantae
D. Fungi.

Answer

**Step-by-Step Solution:**

1. **Understanding Heterotrophic Ingestive Nutrition:**
- Heterotrophic ingestive nutrition is a mode of nutrition where organisms obtain their food by ingesting other organisms or organic matter. This involves breaking down complex organic molecules into simpler forms.

2. **Identifying the Types of Heterotrophic Nutrition:**
- Heterotrophic nutrition can be categorized into several types:
- **Saprotrophic:** Organisms that feed on dead and decaying matter.
- **Holozoic:** A complex form of nutrition where organisms ingest food, digest it, and absorb the nutrients. This is typically seen in animals.
- **Parasitic:** Organisms that depend on a host for nutrition.
- **Absorptive:** Organisms that absorb organic matter directly.

3. **Analyzing the Options:**
- **Monera:** This kingdom includes bacteria, which primarily exhibit parasitic or absorptive modes of nutrition. They do not typically show ingestive nutrition.
- **Animalia:** This kingdom consists of animals that have well-developed digestive systems and exhibit holozoic nutrition, which is a form of ingestive nutrition.
- **Plantae:** Plants primarily perform autotrophic nutrition through photosynthesis, meaning they produce their own food and do not exhibit heterotrophic ingestive nutrition.
- **Fungi:** Fungi can be saprotrophic or parasitic but do not typically exhibit ingestive nutrition.

4. **Conclusion:**
- Based on the analysis, the only kingdom that exhibits heterotrophic ingestive nutrition is **Animalia**.

**Final Answer:** The correct answer is **Animalia**.
