<span>Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water</span>

Chemical composition of the Sun and the movement of galaxies.
Astronomers are scientists who study the universe and the objects within it such as the sun, galaxies, stars, planets, star forming regions, and the evolution of the universe. Chemical composition of the Sun and the movement of galaxies are the types of evidence that astronomers use to estimate the age of the universe and stars. Astronomers detect the movement of galaxies by viewing its light spectrum. Astronomers can measure the expansion rate of the universe accurately by taking the measurements of many galaxies. Also, the chemical composition of the sun gives astronomers some idea about the age of the universe and stars.
