starts with sunlight and photosynthesis if you are talking about plants
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Answer:Water molecules are split apart.
Explanation: In the light dependent reactions of photosynthesis, sunlight provides the energy for splitting of water into its components: hydrogen and oxygen. This reaction is known as the photolysis of water. The oxygen is evolved as a byproduct. In this light dependent reactions, the light energy absorbed is used for the splitting of water molecules and it is also conserved as ATP and NADPH which are used to drive the carbon fixation reactions of photosynthesis.
