Question

You may notice that the same organism can fit into different groups depending on the criterion you choose. This leads to an important question: how do scientists decide which features to use while grouping the living organisms? This question leads us to the idea of classification, a systematic way of organising the Earth’s living diversity.

Answer 1

Scientists group living organisms based on their similarities and differences in characteristics such as cell structure, body organisation, mode of nutrition, reproduction, and evolutionary relationships. These features help in the systematic classification of organisms.
