Answer:
Animalia
Step-by-step explanation:
If we talk about Eukaryotic and multi-cellular organisms, only three kingdoms come in mind, Plantae, Animalia and Fungi.
In plantae, plants are able to make their own food through the process of Photosynthesis.
Fungi are heterotrophic like animals but they cannot move from one place to another.
Animalia is a Kingdom where organisms are able to move from one place to another but are not able to synthesize their own food like humans, Lions, monkeys etc.
Therefore answer in Animalia
