Explanation:

Charles Darwin is the author of the theory of evolution and natural selection recognized today. He was a very important scientist, changing the way human beings thought of living beings and the evolutionary processes between them.

According to him, plants and animals change slowly over time. This all occurs through the process of natural selection where the individuals most adapted to the region survive and have the ability to reproduce, while the less adapted die without leaving descendants. The most adapted organisms transmit their characteristic adapted to their descendants, allowing the species to evolve over time.

the answer is :

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.
