Task: Question Answering
Input (English): Passage: Light-independent reactions -- This process occurs without light availability. Plants do not carry out the Calvin cycle during nighttime. They instead release sucrose into the phloem from their starch reserves. This process happens when light is available independent of the kind of photosynthesis (C3 carbon fixation, C4 carbon fixation, and Crassulacean acid metabolism); CAM plants store malic acid in their vacuoles every night and release it by day to make this process work. They are also known as dark reactions.
Question: does the calvin cycle only occur at night
Output (English): 0
