Animals are heterotrophic. Unlike plants and algae which are autotrophic, the animals depend on another organism for food. Animal carnivores, for instance, are adapted to hunting their prey while others scavenge for animal carcasses or remains. Others feed on plants and as such are referred to as herbivores. Omnivores are animals that feed on both plants and animals. Most animals have an elaborate digestive system in the form of an internal chamber (a digestive tract) that processes ingested food to extract nutrients from it and then released it from the body in the form of excreta or a waste matter. Many animals have a mouth for ingestion and an anus for excretion. Other animals (e.g. Platyhelminthes, cnidarians) have only one opening that serves both as a mouth and an anus. Poriferans, in contrast, lack a digestive system.
