How could a change in the carbon cycle lead to a change in the water cycle? (Give me an example of an increase in one process leading to an increase or decrease in the process of the other cycle)

Higher rates of carbon fixation lead to increased respiration, energy production and CO2 + H2O excretion.  

Explanation:

Inorganic carbon is fixed into high-energy polysaccharides by producers during photosynthesis and used by consumers in respiration to produce fuel, where it is produced as a waste product, along with water.

In photsynthesis...

In respiration..

Thus, changes in photosynthesis affect the ability of other organisms to respire and produce water. More fixation directly leads to increased respiration, production of ATP, and CO2 + H2O excretion.  

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
