The Five Kingdoms taxonomy of Robert Whittaker is based nutritive modes. Animal is an ingestive mode kingdom. Plant is a photosynthetic kingdom. Fungi is an absorbing nutritive kingdom. Animal, Plant and Fungi are multicellular organisms. Protist are unicellular eukaryotes. Monera are unicellular prokaryotes. A domain is grouping of kingdoms. Eukaryota is a domain of all life except Monera (bacteria).
