Question

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

Explanation:

• Plantae are mostly autotrophic (photosynthetic), not both autotrophic and heterotrophic.
• Animalia are exclusively heterotrophic.
• Archaebacteria include both autotrophic and heterotrophic organisms, but Animalia do not, so this pair is incorrect.
• Protista (e.g., algae: autotrophic; amoebas: heterotrophic) and Eubacteria (e.g., cyanobacteria: autotrophic; E. coli: heterotrophic) both contain organisms that are either autotrophic or heterotrophic.

Answer:

Protista and Eubacteria
