Question

Which best represents an example of carbon fixation?

Answer 1

The option that best represents an example of carbon fixation would be the incorporation of CO2 into organic molecules.

Carbon fixation refers to the process of converting atmospheric carbon, mostly in the form of carbon dioxide, to organic molecules in the form of carbohydrates, usually in living organisms.

In living organisms carbon is fixed either via photosynthesis or chemosynthesis.

During the photosynthetic process, inorganic carbon in the form of carbon dioxide combines with water and is converted into carbohydrates in the presence of radiant energy. The process usually happens in green plants.

During chemosynthesis, carbon dioxide reacts with H2S instead of water to arrive at carbohydrates. The process usually happens in chemosynthetic bacteria.

Answer 2

The process of photosynthesis is the best example of carbon fixation.

In the process of photosynthesis, energy from sunlight drives the carbon fixation pathway. photosynthesis process is used by the primary producers such as plants, algae, and cyanobacteria. They contain green pigment named chlorophyll that used the Calvin cycle to fix carbon.

The carbon atom present in the atmosphere in the form of carbondioxide gas fixes by the producers in the form of glucose which have 6 carbon atoms so we can conclude that photosynthesis is the best example of carbon fixation.
