Evaporation will probably be the next step. The water cycle consists of a few steps. Most of which you should know. But yeah evaporation would most likely be next.
B) The sun. Most energy can be traced back to the sun in general.

Answer:
Finally, the chemical messenger is taken back into the presynaptic neuron, ready to be used again. As levels of the neurotransmitter in the synapse decrease, the stimulation of the postsynaptic nerve ends.
Explanation:
The synapse is the space between two neurons. Through this space, neurons communicate.
An action potential causes the release of neurotransmitters from the presynaptic neuron; if there are enough of these specific neurotransmitters to bind to receptors on the postsynaptic neuron, they do and an action potential is now generated on this neuron.
This communication between two neurons must end once it's happened. In order for it to end, the synapse must be free of neurotransmitters. One mechanism to do so is for the neurotransmitters to be taken back into the presynaptic neuron.
Plants take in carbon dioxide as a part of photosynthesis. Their waste product is oxygen and so it continues. I can't help with the water cycle though... sorry. I hoped this helped :p
