Photosynthesis and cellular respiration are related in that; photosynthesis is a process that is tasked in making glucose which is then used in cellular respiration to make ATP. The glucose is then converted to carbon dioxide during cellular respiration, which is used in photosynthesis. Water on the other hand is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
The tilt of the earth changing would affect the distance to the sun. This, the radiation from the sun, and resulting temperatures, would change as well.
