Characteristics of animal kingdom

Answer 1

Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and usually multicellular(although see Myxozoa), which separates them from bacteria and most protists. They are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls. All animals are motile,if only at certain life stages. In most animals, embryos pass through a blastula stage, which is a characteristic exclusive to animals.

Answer 2

The animal kingdom is characterized by multicellularity, heterotrophic nutrition, and the absence of cell walls. Animals are also known for their ability to move, reproduce sexually, and exhibit a diverse range of body structures and functions.
