Final answer:
The three-toed sloth belongs to the Animalia kingdom, a kingdom characterized by multicellular, heterotrophic organisms that obtain food by ingestion. It is distinct from the Sphenodontia group from the Mesozoic Era, an example of diversity within this kingdom.
Step-by-step explanation:
The three-toed sloth, a remarkable creature of the animal kingdom, belongs to the Animalia kingdom. In biological classification, the Animalia kingdom comprises animals differing vastly from one another, such as the slow, leaf-eating three-toed sloth. The Animalia kingdom is characterized by organisms that are multicellular and heterotrophic, meaning they obtain food by ingestion. Although your question may be about the sloth, an additional fact is that the Sphenodontia, a group from the Mesozoic Era, also belong to this kingdom, although they are more closely linked to birds and turtles.
