What are the product of dark phase?

The dark phase of photosynthesis, also known as the Calvin cycle, primarily produces glucose and other carbohydrates using carbon dioxide and energy derived from ATP and NADPH generated in the light-dependent reactions. During this phase, carbon fixation occurs, where carbon dioxide is incorporated into organic molecules, ultimately leading to the synthesis of sugars. These products serve as energy sources for plants and, indirectly, for other organisms in the food chain.
