The link between photosynthesis and cellular respiration is an inverse relationship, both are opposites of each other. Photosynthesis is the process by which carbon dioxide is converted into organic compounds from sunlight. The most frequent compound is sugar. Photosynthesis occurs in plants, algae, and some bacteria. Cellular respiration, in contrast, takes glucose (sugar) and other organic compounds oxidizing them to create carbon dioxide. Each cycle depends on one another in order for the "entire cycle" to take place. The completed cycle ensures life continues to exist on the planet. Both are necessary for living organisms.
