Study of all living organisms is made possible by this aspect of taxonomy

Options

A. Identification
B. Systematics
C. Classification
D. Nomenclature

Answer

To answer the question "Study of all living organisms is made possible by this aspect of taxonomy," we need to analyze the different aspects of taxonomy provided in the options: identification, systematics, classification, and nomenclature.

### Step-by-Step Solution:

1. **Understanding Taxonomy**: Taxonomy is the science of classification of living organisms. It involves various aspects such as identification, classification, nomenclature, and systematics.

2. **Analyzing the Options**:
- **Identification**: This refers to the process of determining the identity of an organism, i.e., figuring out which species it belongs to. While identification is important, it is just one part of the broader study of living organisms.
- **Systematics**: This is a comprehensive field that includes the study of the diversity of organisms and their evolutionary relationships. It encompasses identification, classification, and nomenclature, making it a holistic approach to studying all living organisms.
- **Classification**: This involves organizing organisms into groups based on shared characteristics. While classification is essential for understanding relationships among organisms, it does not cover the entire scope of studying all living organisms.
- **Nomenclature**: This is the system of naming organisms. It is a vital aspect of taxonomy, but it is limited to naming and does not encompass the broader study of organisms.

3. **Conclusion**: Among the options, **systematics** is the aspect of taxonomy that allows for the comprehensive study of all living organisms, as it includes identification, classification, and nomenclature, along with understanding evolutionary relationships.

### Final Answer:
The study of all living organisms is made possible by **systematics**.
