The chemical energy stored in atp during photosynthesis is released during the dark phase to
produce o2
release energy for the "light"
produce a carbohydrate from co2
produce co2

The chemical energy stored in ATP during photosynthesis is released during the dark phase to produce O2. This is the exchange cycle between the plants and animals. Animals give off carbon dioxide (CO2) as an excess waste while the plants give off oxygen (O2).

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
