Tertiary consumers feed on heterotrophs since heterotrophs are secondary consumers, therefore tertiary consumers feed on those. It also depends on what kind of heterotroph one has.
The animal kingdom consists of only multicellular heterotrophs.
Protista
The kingdom that includes autotrophs, heterotrophs, unicellular, and multicellular organisms is the Kingdom Protista. This kingdom is a diverse group of eukaryotic organisms that do not fit neatly into the other major kingdoms.
Protista, of course.
The Fungi kingdom includes multicellular heterotrophic organisms.
Fungi
The kingdom of protists has both heterotrophs, autotrophs, and uni/multicellular organisms.
The animal kingdom consists of only multicellular heterotrophs.
The kingdom that includes both autotrophs and heterotrophs is the Plantae kingdom. Autotrophs in this kingdom are represented by plants that produce their own food through photosynthesis, while heterotrophs in the form of fungi are also included in this kingdom that rely on other organisms for nutrients.
Animalia.

Heterotrophs are animals that cannot make their food, like plants can. the most common kingdom of heterotrophs is the Animalia kingdom. Hope this helps.
Protista, of course.
The Fungi kingdom includes multicellular heterotrophic organisms.
The Animalia kingdom includes only multicellular heterotrophs, which are organisms that cannot produce their own food and rely on consuming other organisms for energy. This kingdom encompasses a wide variety of species, from insects to mammals, that share common characteristics such as being composed of eukaryotic cells and having specialized tissues.
