What is eukarya domain?
This domain consists of "Protista," Fungi, Plantae, and Animalia. Most of them are multicellular. Fungi decompose their food, Animalia consumes their food (vegetables, meat, or carcasses), and Plantae makes their own food. "Protista" is not exactly a true clade, as they have multiple descendants in different clades. This is just a brief overview, though. :)
