Which Organisms Obtain Carbon from CO₂

Question

Which organisms obtain carbon from CO2?
A) auxotrophs
B) heterotrophs
C) autotrophs
D) chemotrophs

Accepted Answer

Autotrophs are organisms that can produce their own food using light, water, carbon dioxide, or other chemicals. Since the question mentions obtaining carbon from a chemical formula (CO₂), which seems to be a placeholder for carbon sources like carbon dioxide, autotrophs are the correct answer because they can convert carbon dioxide into organic compounds through processes like photosynthesis.
