3. **Consider the Options**: The options provided are:
- Classification
- Taxonomy
- Systematics
- Identification

4. **Define Each Option**:
- **Classification**: This refers to the process of arranging organisms into categories based on shared characteristics.
- **Taxonomy**: This is the science of naming, describing, and classifying organisms. It encompasses classification, identification, and nomenclature.
- **Systematics**: This is a broader field that studies the evolutionary relationships among organisms, focusing on their natural variation and classification.
- **Identification**: This is the process of recognizing and naming organisms based on their characteristics.

5. **Determine the Correct Answer**: Since the question specifically asks about the process of grouping organisms into different taxa, the most appropriate term is "Taxonomy." Taxonomy includes classification as a part of its broader scope.
