Nutrition in Protista is

Options

A. Phagotrophic
B. Saprotrophic
C. Autotrophic
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Protista**: The kingdom Protista consists of a diverse group of organisms, primarily unicellular, such as amoeba. It includes various types of nutrition methods.

2. **Types of Nutrition in Protista**:
- **Phagotrophic Nutrition**: This is a type of nutrition where organisms ingest solid food particles. In this process, digestion occurs inside the cell. For example, amoeba uses phagotrophic nutrition by engulfing food particles.

- **Saprotrophic Nutrition**: In this type, organisms obtain nutrients by decomposing organic matter. Digestion occurs outside the cell, and this type of nutrition is commonly found in fungi and some parasites.

- **Autotrophic Nutrition**: Autotrophic organisms produce their own food through processes like photosynthesis or chemosynthesis. They do not rely on other organisms for their nutrition.

3. **Conclusion**: The question asks about the types of nutrition present in Protista. The correct answer is that Protista can exhibit phagotrophic, saprotrophic, and autotrophic nutrition methods, but the most common type associated with many protists, especially those like amoeba, is phagotrophic.

4. **Final Answer**: Nutrition in Protista can be classified as phagotrophic, saprotrophic, and autotrophic, with phagotrophic being a significant method in many protists.
