Answer:
Some limitations of using a classification system to categorize living things include:
1. Subjectivity: Classifying organisms can sometimes be subjective, as different scientists may interpret characteristics differently or prioritize different criteria for classification.
2. Hybridization: Some organisms exhibit characteristics of multiple categories or can interbreed with organisms from other categories, making classification challenging.
3. Evolutionary Changes: Organisms evolve over time, leading to changes in characteristics that may blur traditional classification boundaries.
4. Lack of Intermediates: Some organisms may possess characteristics that do not neatly fit into existing categories, leading to difficulties in classification.
