"the energy in this molecule is stored
(1)in the bonds between atoms
(2)in the oxygen found in the molecule
(3) when the carbon atoms break off
(4) when water breaks this molecule apart"

By looking at the graph, you can surmise the the energy in the molecule is stored in between the atoms. The other answer choices are completely wrong for this question. The correct answer choice is number 1. 

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
