Step 1:I'll solve this problem step by step, following the specified formatting guidelines:
Step 2:: Understand Carbon Fixation
This is a crucial biological process that transforms atmospheric $$CO_{2}$$ into energy-rich organic molecules.
Carbon fixation is the process by which inorganic carbon (typically carbon dioxide) is converted into organic compounds by living organisms.
Step 3:: Analyze the Options
Let's examine each option: A. Photosynthesis in plants B. Respiration in animals C. Decomposition of organic matter D. Combustion of fossil fuels
Step 4:: Evaluate Carbon Fixation Characteristics
- It typically involves capturing $$CO_{2}$$ and incorporating it into organic molecules
- Carbon fixation requires converting inorganic carbon to organic carbon - This process is most associated with autotrophic organisms that can produce their own food
Step 5:: Identify the Correct Process
- Use light energy to convert $$CO_{2}$$ into glucose
Photosynthesis is the primary biological process of carbon fixation. During photosynthesis, plants: - Create organic compounds from inorganic carbon
Step 6:: Eliminate Incorrect Options
- Respiration breaks down organic molecules, not fixing carbon - Decomposition returns carbon to the environment - Combustion releases carbon, not fixing it
Final Answer
Photosynthesis in plants is the best example of carbon fixation.
