Kingdom Animalia either directly or indirectly depend on plants for food (Classified as Herbivores and Carnivores).
They lack a cell wall and digest their food in an internal cavity and store food reserves as glycogen or fat.
Their mode of nutrition is holozoic – by ingestion of food.
They follow a definite growth pattern and grow into adults with definite shape and size.
Higher forms show elaborate sensory and neuromotor mechanism. Most of them are capable of locomotion.
The sexual reproduction is by copulation of male and female followed by embryological development.
