Why is classification of living organisms needed?

Classification of living organisms is needed to organise the large variety of life forms into groups based on their similarities and differences. It makes the study, identification, and comparison of different organisms easier and more systematic.

Since millions of organisms exist on Earth, scientists classify them according to common characteristics such as structure, body features, method of obtaining food, reproduction, and habitat. For example, plants and animals can be grouped based on shared features that help distinguish one group from another.

Classification provides a scientific method to understand relationships among organisms and study biodiversity in an organised way.
