Which type of organism uses CO2 as their carbon source?
Understand the Problem
The question is asking to identify the type of organism that utilizes carbon dioxide (CO2) as their primary carbon source. This relates to biological classifications of organisms based on their carbon sources and metabolic processes.
Answer
Autotrophs, such as photoautotrophs or chemoautotrophs.
Organisms that use CO2 as their carbon source are called autotrophs, specifically photoautotrophs or chemoautotrophs.
Answer for screen readers
Organisms that use CO2 as their carbon source are called autotrophs, specifically photoautotrophs or chemoautotrophs.
More Information
Autotrophs are organisms that can produce their own food by using carbon dioxide as a carbon source. Photoautotrophs use sunlight to convert CO2 into organic material via photosynthesis, while chemoautotrophs obtain energy from inorganic substances.
Tips
Confusing photoautotrophs, which use light for energy, with chemoautotrophs, which rely on chemical reactions, is a common mistake.
