Living organisms share the following features except that they

Options

A. are formed of protoplasm
B. can prepare food
C. respire
D. reproduce

Answer

To solve the question regarding the features shared by living organisms, we need to analyze each option provided and determine which one is not common to all living organisms.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) They are formed of protoplasm
- B) They can prepare food
- C) They respire
- D) They reproduce

2. **Analyze Option A**:
- **Explanation**: Protoplasm is the living substance of the cell, which includes the cytoplasm and the nucleus. All living organisms, whether unicellular or multicellular, are made up of cells that contain protoplasm.
- **Conclusion**: This feature is common to all living organisms.

3. **Analyze Option B**:
- **Explanation**: The ability to prepare food is a characteristic of autotrophs (like plants) which can perform photosynthesis. Heterotrophs (like animals) cannot prepare their own food and rely on consuming other organisms.
- **Conclusion**: This feature is not common to all living organisms, as not all can prepare their own food.

4. **Analyze Option C**:
- **Explanation**: Respiration is a vital process for all living organisms, as it involves the conversion of food into energy. All organisms, whether aerobic or anaerobic, respire to obtain energy.
- **Conclusion**: This feature is common to all living organisms.

5. **Analyze Option D**:
- **Explanation**: Reproduction is essential for the continuation of species. All living organisms have the ability to reproduce, either sexually or asexually.
- **Conclusion**: This feature is also common to all living organisms.

6. **Final Conclusion**: The only feature that is not shared by all living organisms is the ability to prepare food. Therefore, the correct answer is:
- **B) They can prepare food**.
