Verified step by step guidance

Understand the concept of carbon fixation: Carbon fixation is the process by which inorganic carbon (typically in the form of carbon dioxide) is converted into organic compounds by living organisms. The most common example of carbon fixation is photosynthesis.

Identify the role of photosynthesis in carbon fixation: During photosynthesis, plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using sunlight. This process incorporates carbon dioxide into organic molecules, which is the essence of carbon fixation.

Differentiate between the given processes: Hydrolysis involves breaking down compounds by adding water, hydrogenation involves adding hydrogen to compounds, and dehydration synthesis involves joining two molecules by removing water. None of these processes involve the conversion of inorganic carbon to organic carbon.

Recognize that photosynthesis is the only process among the options that involves carbon fixation: Photosynthesis is the process that incorporates carbon dioxide into organic compounds, making it the correct example of carbon fixation.

Conclude that photosynthesis is the correct answer: Based on the understanding of carbon fixation and the roles of the other processes, photosynthesis is the process that exemplifies carbon fixation.
