What is one of the major categories into which living organisms are classified?

Living organisms are classified into hierarchical categories that help organize the vast diversity of life. One of the major categories in this classification system is the kingdom. The kingdom is a high-level taxonomic rank that groups together organisms sharing fundamental similarities. For example, all animals are classified within the Kingdom Animalia, while plants are classified within the Kingdom Plantae. This classification helps scientists and researchers communicate about different life forms based on shared characteristics and evolutionary relationships.

The kingdom category is foundational in biological classification, serving as a broad grouping before further divisions into phyla, classes, orders, and beyond. Each subsequent level of classification becomes increasingly specific, allowing for a detailed understanding of the relationships among organisms.
