Ingestive nutrition is

Options

A. Heterotrophic
B. Autotrophic
C. Saprotrophic
D. Holophytic.

Answer

### Step-by-Step Solution

1. **Understanding Ingestive Nutrition**: Ingestive nutrition refers to a mode of nutrition where organisms take in food through ingestion. This typically involves consuming solid or liquid food, which is then processed internally.

2. **Identifying Types of Nutrition**: Organisms can be classified based on their nutritional modes into two main categories:
- **Autotropic Nutrition**: Organisms that can synthesize their own food (e.g., plants and certain bacteria).
- **Heterotropic Nutrition**: Organisms that depend on other organisms for food.

3. **Exploring Heterotropic Nutrition**: Heterotropic nutrition is further divided into three types:
- **Saprotropic Nutrition**: Organisms that feed on dead and decaying matter.
- **Parasitic Nutrition**: Organisms that derive nutrients from a host organism.
- **Holozoic (or Holophytic) Nutrition**: Involves the ingestion of solid or liquid food, followed by internal processing.

4. **Identifying the Correct Answer**: Since ingestive nutrition involves the ingestion and internal processing of food, the correct classification for ingestive nutrition is **Holozoic (or Holophytic) Nutrition**.

### Final Answer
Ingestive nutrition is best classified as **Holozoic Nutrition**.
