Both of them are different, so both cycles work together. The carbon cycle lets out carbon dioxide and it then transfers it into the trees. The trees get the nitrogen and the cycle starts again.
Water cycle is the cycle that H2O molecules go through. The nitrogen cycle is the cycle that nitrogen goes through as it changes from nitrate to nitrite to ammonia, all by bacterias in the soil.
Carbon Cycle: CO2 in the air get taken in by plants through photosynthesis. Carbon is in plant. Animals eat the plant. Carbon is in animal. Animal droppings contain carbon. Decomposers break down...
