Conventional taxonmic methods are not suitable for identifying

Options

A. Amphibian species
B. Insect species
C. Microbial species
D. Gymnospermic species

Answer

### Step-by-Step Solution:

1. **Understanding Conventional Taxonomic Methods**:
- Conventional taxonomic methods are traditional ways of classifying organisms based on observable characteristics and the number of species. These methods are generally effective for identifying and classifying plants, animals, and fungi.

2. **Identifying the Groups Mentioned**:
- The question lists several groups: amphibians, insects, microbial species, and gymnospermic species. We need to analyze why conventional methods may not be suitable for these groups.

3. **Analyzing Each Group**:
- **Amphibians and Insects**: Both of these groups fall under the animal kingdom and can typically be classified using conventional methods. Therefore, they are not the primary concern for this question.
- **Gymnospermic Species**: These are plants and can also be classified using conventional methods, so they are not the focus either.
- **Microbial Species**: This group includes prokaryotes (like bacteria) which have a vast number of species. The diversity and microscopic nature of these organisms make it challenging to identify them using conventional methods.

4. **Conclusion**:
- Since conventional taxonomic methods are not suitable for identifying microbial species due to their vast diversity and the difficulty in counting and classifying them, the correct answer to the question is microbial species.

### Final Answer:
Conventional taxonomic methods are not suitable for identifying **microbial species**.
