Textbook Question
Carbon fixation is the conversion of _____ into organic compounds.
Verified step by step guidance1
Understand the concept of carbon fixation: it is a biochemical process where inorganic carbon is converted into organic molecules.
Identify the source of inorganic carbon in biological systems, which is typically carbon dioxide (CO\_2).
Recognize that during carbon fixation, CO\_2 is incorporated into organic compounds such as sugars.
Recall that this process is fundamental in photosynthesis, where plants, algae, and some bacteria convert CO\_2 into glucose and other organic molecules.
Therefore, the blank in the statement should be filled with 'carbon dioxide' as the inorganic molecule converted into organic compounds.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Carbon Fixation
Carbon fixation is the biochemical process by which inorganic carbon, typically in the form of carbon dioxide (CO2), is converted into organic molecules. This process is fundamental to autotrophic organisms, enabling them to synthesize carbohydrates and other compounds necessary for growth.

Inorganic Carbon Sources
Inorganic carbon sources, primarily carbon dioxide (CO2), serve as the raw material for carbon fixation. These molecules lack carbon-hydrogen bonds and must be transformed into organic forms to be utilized by living organisms for energy and structural components.
