In comparison to many other organisms bacteria as a group show :-

Options

A. Most extensive reproductive diversity
B. Most extensive metabolic diversity
C. Most supressive metabolic diversity
D. Most extensive dividing activity

Answer

**Step-by-Step Solution:**

1. **Understanding Bacteria**: Bacteria are unicellular organisms that exhibit a wide range of metabolic processes. They can be classified based on how they obtain energy and nutrients.

2. **Types of Bacteria**:
- **Autotrophic Bacteria**: These bacteria can produce their own food. They can be further divided into:
- **Photosynthetic Autotrophs**: These bacteria, like green bacteria, use sunlight to synthesize food through photosynthesis.
- **Chemosynthetic Autotrophs**: These bacteria obtain energy by oxidizing inorganic substances, allowing them to produce food without sunlight.

3. **Metabolic Diversity**: Bacteria show extensive metabolic diversity. This means they can utilize a variety of substances for energy and can perform various biochemical processes. This diversity is greater than that seen in many other organisms.

4. **Comparison with Other Organisms**: When comparing bacteria to other organisms, it becomes clear that bacteria have a wider range of metabolic pathways. This includes the ability to thrive in extreme environments and utilize a variety of substrates for energy.

5. **Conclusion**: Based on the understanding of bacterial diversity, the correct answer to the question is that bacteria, as a group, show the most extensive metabolic diversity.

**Final Answer**: B - Most extensive metabolic diversity.
