General characteristics of the Kingdom Animalia are as follows: Animals are eukaryotic, multicellular and heterotrophic organisms. They have multiple cells with mitochondria and they depend on other organisms for food.Habitat-Most of the animals inhabit seas, fewer are seen in fresh water and even fewer on land.he Kingdom Animalia is characterized by eukaryotic and heterotrophic organisms. They are multicellular and lack cell wall. They depend directly or indirectly of plants for their food. Food is ingested and digested in their internal cavity and food reserves are stored as glycogen or fat.
 These reduced carbon compounds can be used as an energy source by  the autotroph and provide the energy in food consumed by  heterotrophs. More than 95% of all organisms are heterotrophic.[2]   A heterotroph is an organism that requires organic  substrates to get its carbon for growth and development.A  heterotroph is known as a consumer in the food chain. Contrast with autotrophs which use inorganic carbon dioxide or  bicarbonate as sole carbon source. All animals are heterotrophic,  as well as fungi and many bacteria.These reduced carbon compounds can be used as an energy source by  the autotroph and provide the energy in food consumed by  heterotrophs.
