Which process provides an eventual carbon source for glycolysis?

Photosynthesis

Explanation:

Glycolysis is metabolic process which is considered a part of the cellular respiration. The glycolysis process breakdown the glucose molecule into pyruvate molecule which is utilised into the Citric acid cycle to form energy molecules. Glycolysis catabolism the glucose molecule into ten steps mediated by enzyme action.

The glucose molecule which enter the biogeochemical cycle is formed in the green plants by the process of photosynthesis. Photosynthesis is a process which uses sunlight and water to synthesize energy molecules.

Thus, Photosynthesis is the correct answer.
