The mode of nutrition where organisms depend on other organisms for their food requirements is called heterotrophic nutrition. Animals are called consumers as they depend on autotrophs for their nutrition requirements. So nutrition in animals is heterotrophic in nature.
Now, this dependence on other animals may be of different types. Some organisms such as fungi break down the food outside the body and then absorb it. There are some more organisms who are parasites living on other animals and plants.
In humans, the type of nutrition that is found is called holozoic nutrition. It simply means eating or ingesting food and then digesting the food, to get the required nutrition. The digested food gets absorbed and assimilated, and finally, any waste is excreted outside.
When animals including humans ingest food particles, they have some form of digestive systems to break down the complex food particles into simpler particles. The digestive system varies from the lower organisms such as amoeba and paramecium when compared to other higher-order animals such as fishes, amphibians, humans etc.
