Question

which kingdom(s) include organisms that are autotrophic or heterotrophic?
○ plantae
○ animalia
○ archaebacteria and animalia
○ protista and eubacteria

Explanation:

• Plantae: Mostly autotrophic (photosynthesis), not heterotrophic.
• Animalia: Only heterotrophic (consume others).
• Archaebacteria and Animalia: Archaebacteria can be auto/hetero, but Animalia is only hetero—this combination is incorrect.
• Protista and Eubacteria: Protista (e.g., algae - autotrophic, protozoa - heterotrophic) and Eubacteria (some autotrophic like cyanobacteria, some heterotrophic) include both autotrophic and heterotrophic organisms.

Answer:

D. Protista and Eubacteria
