Both autotrophic and heterotrophic nutrition is observed in

Options

A. 1)Animalia
B. 2)Protista
C. 3)Fungi
D. 4)Plantae

Answer

To solve the question "Both autotrophic and heterotrophic nutrition is observed in," we will analyze the options provided and determine which one includes organisms that exhibit both types of nutrition.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Autotrophic Nutrition**: This is a mode of nutrition where organisms can produce their own food, typically through photosynthesis (e.g., plants).
- **Heterotrophic Nutrition**: This is a mode of nutrition where organisms cannot produce their own food and rely on other organisms for sustenance (e.g., animals).

2. **Evaluate Each Option**:
- **Option 1: Animalia**:
- Organisms in this kingdom are primarily heterotrophic. They depend on other organisms for food.
- **Conclusion**: This option is incorrect.

- **Option 2: Protista**:
- This kingdom includes a diverse range of organisms. Some protists, like algae, can perform photosynthesis (autotrophic), while others, like amoebas, are heterotrophic.
- **Conclusion**: This option is correct as it contains both autotrophic and heterotrophic organisms.

- **Option 3: Fungi**:
- Fungi are primarily heterotrophic, as they absorb nutrients from their surroundings and do not perform photosynthesis.
- **Conclusion**: This option is incorrect.

- **Option 4: Plantae**:
- Organisms in this kingdom are primarily autotrophic, as they produce their own food through photosynthesis.
- **Conclusion**: This option is incorrect.

3. **Final Answer**:
- The correct option is **Option 2: Protista**, as it includes organisms that exhibit both autotrophic and heterotrophic nutrition.
