Mode of nutrition in green plants is called :

Options

A. heterotrophic
B. holozoic
C. Autotrophic
D. saprotrophic

Explanation

### Step-by-Step Solution:

1. **Understanding Nutrition in Plants**:
- Green plants require nutrients to grow, develop, and repair themselves. This process involves taking in food.

2. **Role of Green Plants**:
- Green plants are known as primary producers because they produce their own food. This is a crucial role in the ecosystem.

3. **Photosynthesis**:
- The process through which green plants make their own food is called photosynthesis. During this process, plants use sunlight, carbon dioxide, and water to create glucose and oxygen.

4. **Definition of Autotrophic Nutrition**:
- The mode of nutrition in which organisms produce their own food is termed "autotrophic." This is the correct term for the nutrition mode in green plants.

5. **Distinction from Other Modes of Nutrition**:
- It is important to differentiate autotrophic nutrition from other types such as:
- **Heterotrophic**: Organisms that depend on other organisms for food.
- **Holozoic**: A type of heterotrophic nutrition where organisms ingest solid food.
- **Saprophytic**: Organisms that feed on dead and decaying organic matter.

6. **Conclusion**:
- Therefore, the mode of nutrition in green plants is called **autotrophic nutrition**.

### Final Answer:
The mode of nutrition in green plants is called **autotrophic nutrition**.
