Verified step by step guidance

1. Understand that taxonomy is the science of classifying organisms based on shared characteristics.
2. Recognize that morphology refers to the form and structure of organisms, which is a key trait used in classification.
3. Identify genetic makeup as another crucial trait, involving the analysis of DNA sequences to determine evolutionary relationships.
4. Acknowledge the ecological niche, which describes the role an organism plays in its environment, as a significant factor in classification.
5. Differentiate these traits from others like reproductive method, speed, and intelligence, which are not typically used in taxonomy.
