How will you classify living beings?

Living beings can be classified into different groups based on their characteristics, such as cellular structure (prokaryotic vs. eukaryotic), mode of nutrition (autotrophs vs. heterotrophs), and number of cells (unicellular vs. multicellular). Additionally, living beings can be classified into domains (Bacteria, Archaea, Eukarya) and kingdoms (e.g., Animalia, Plantae, Fungi) based on evolutionary relationships.
