Microorganisms play an important role in our lives. Various microorganism are used in preparing food and beverages for both domestic and industrial use. They can also prove harmful to us as they cause a number of diseases in human, plants and animals. Microorganisms also spoil clothing and leather products.
Mixotrophic nutrition is shown by

Options

A. Euglena
B. Paramecium
C. Entamoeba
D. Amoeba

Explanation

**Step-by-Step Solution:**

1. **Understanding Microorganisms**: Microorganisms are tiny living organisms that can be beneficial or harmful. They play significant roles in food production, disease causation, and spoilage of materials.

2. **Identifying Nutrition Types**: There are different types of nutrition among microorganisms. The question specifically asks about "mixotrophic nutrition."

3. **Defining Mixotrophic Nutrition**: Mixotrophic nutrition refers to organisms that can obtain their food in more than one way. This means they can produce their own food (autotrophic) and also consume other organisms (heterotrophic).

4. **Analyzing the Options**: The options given are:
- Euglena
- Paramecium
- Amoeba
- Entamoeba

5. **Evaluating Euglena**: Euglena is known to be mixotrophic. It can perform photosynthesis in the presence of sunlight (autotrophic) and can also absorb nutrients from its environment when sunlight is not available (heterotrophic).

6. **Evaluating Other Options**:
- Paramecium, Amoeba, and Entamoeba are primarily heterotrophic. They rely on consuming other organisms for their nutrition and do not perform photosynthesis.

7. **Conclusion**: Since Euglena is the only organism among the options that exhibits mixotrophic nutrition, it is the correct answer.

**Final Answer**: Euglena shows mixotrophic nutrition.
