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.
This contrasts with autotrophs, such as plants, algae and  some bacteria, that can use energy from sunlight (photosynthesis)  or inorganic compounds to produce organic compounds such as  carbohydrates, fats, and proteins from inorganic carbon dioxide.   Humans are a good example of heterotrophs.That's why we eat a lot  of plants.   A heterotroph is any organism that requires organic subtrates in  order to survive.    Basically, a heterotroph is a consumer which must eat other animals  and cannot produce its own food. It is referring to the consumers in the food chain, such as  animals,fungi and many bacteria. More scientifically, it's the life  form that uses organic carbon for growth. This contrasts with  autotrophs, which are the producers, mainly plants, in the food  chain.
