Kingdom Animalia Characteristics. 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.his kingdom does not contain prokaryotes. All the members of this kingdom are multicellular, eukaryotes. They are heterotrophs, they depend on other organisms directly or indirectly for food. Most of the animals ingest food and digest in the internal cavity.
This is due to formation of isovaleric acid, believed to be valerian's active ingredient. That's why it is unlikely valerian itself will be developed into an antiepileptic drug, Eadie said. No one in their right mind would do a clinical trial.
