Praxis Elementary Education: Three-Subject Bundle – Science (5905) Practice Test

Taxonomy is the science of classifying living things. It groups organisms based on shared characteristics and arranges them into a hierarchical system—domain, kingdom, phylum, class, order, family, genus, and species. This framework, along with the use of scientific names (binomial nomenclature), helps scientists communicate precisely and study how organisms are related and have evolved. Other fields focus on different ideas: ecology looks at how organisms interact with their environment, anatomy studies the structure of organisms, and physiology examines how their bodies function.
