Detailed explanation-1: -Kingdom Animalia is characterized by heterotrophic, eukaryotic organisms that are multicellular and whose cells lack cell walls.

Detailed explanation-2: -Protista. Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall.

Detailed explanation-3: -The heterotrophic eukaryotic, multicellular organisms lacking a cell wall are included in the Kingdom Animalia. The mode of nutrition of these organisms is holozoic. Animalia Animals are multicellular and move with the aid of cilia, flagella, or muscular organs based on contractile proteins.

Detailed explanation-4: -Kingdom fungi include multicellular, heterotrophic eukaryotes with the chitinous cell wall.

Detailed explanation-5: -Animaliaanimals All members of Animalia are multicellular, and all are heterotrophs (that is, they rely directly or indirectly on other organisms for their nourishment). Most ingest food and digest it in an internal cavity. Animal cells lack the rigid cell walls that characterize plant cells.
