What is the field of study called that involves classifying living things?

The field of study that involves classifying living things is known as taxonomy. This branch of biology focuses on identifying, naming, and categorizing organisms into groups based on shared characteristics. Taxonomy helps scientists understand relationships among species, how they evolve, and their roles within ecosystems. It provides essential frameworks for biological research, conservation efforts, and biodiversity studies.

The other fields mentioned serve different purposes: botany specifically studies plants, ecology examines the relationships between organisms and their environment, and entomology is the study of insects. Each of these disciplines contributes valuable knowledge but does not encompass the broader classification of all living organisms like taxonomy does.
