Question

which of the domains include both autotrophs (can feed themselves) and heterotrophs (eat other organisms)?
a) fungi
b) animalia
c) plantae
d) protista

Explanation:

• Fungi are mostly heterotrophs (decomposers or parasites), so A is incorrect.
• Animalia consists of only heterotrophs (consumers), so B is incorrect.
• Plantae are mostly autotrophs (photosynthetic), though some have heterotrophic adaptations, but the majority are autotrophs and not a mix as the question implies.
• Protista includes both autotrophs (e.g., algae) and heterotrophs (e.g., protozoa that consume other organisms), so D is correct.

Answer:

D) Protista
