potential energy
you will need 2 two input AND gates to do this. connect the output of the first to one input of the second. you now have a three input AND gate. just remember when calculating timing that 2 inputs of the 3 have twice the gate delay of the remaining input, thus the output will have skew and possibly glitches. if timing is critical or glitching can't be tolerated it may be best to use an actual three input AND instead of kludging one.

Kinetic energy converting to gravitational potential energy
It changes constantly, there is no set output. The energy a plant gains from photosynthesis comes from light, so the energy produced changes with more/less sunlight. Also, availability of water, availability of carbon dioxide, temperature and the species of plant are all factors which will effect this. eg. A large oak tree on a bright sunny day will produce a large amount of energy, while on a cold rainy dark day a small holly bush will produce a little energy. Photosynthesis and the energy produced is not a linear process; it chsngrs each time due to all the contributing variables. And by the way, this should be in biology not physics...
Kinetic energy becoming potential energy.
The chemical energy from a tree can be changed into thermal energy when you burn the tree's wood.
The leaves are needed as the tree lives by photosynthesis, which is the conversion of light energy into chemical energy. The sunlight is the energy source caught by the leaves and turned into oxygen and carbohydrates such as sucrose, glucose and starch. Kind of cool when you think about it isn't it ?
A tree absorbs carbon dioxide from the air, and, with the input of energy from sunlight, oxidizes many of the oxygen atoms of the absorbed carbon dioxide to elemental oxygen, which is released into the atmosphere. The carbon and some of the oxygen atoms from the absorbed carbon dioxide are incorporated into the structure of the tree as the tree grows.
You can't. And it's the tree of wisdom, not the tree of life.
