Final answer:
The Calvin cycle is a vital process in photosynthesis that occurs in photosynthetic organisms, converting CO₂ and water into organic compounds like glucose.
Explanation:
The Calvin cycle, also known as the light-independent cycle, exclusively occurs in photosynthetic organisms. This cycle is responsible for converting carbon dioxide and water into organic compounds like glucose. It plays a crucial role in the process of photosynthesis by using energy carriers formed in the light-dependent reactions to fix CO₂ and produce essential molecules.
