Which kingdom(s) include organisms that are autotrophic or heterotrophic?

Protista and Eubacteria both include organisms that can make their own food (autotrophs) as well as organisms that obtain food from other sources (heterotrophs). Animalia contains heterotrophs, while Plantae is generally autotrophic, so neither alone covers both ways of getting food. Therefore, the correct choice is Protista and Eubacteria.
