Yes. Animals and humans have instincts. Every creature does. Most of the time offspring are born in populations that are thriving so their young and their genes can be passed on.
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.
