As you can see, the water in the water cycle begins with the stream. The water from the stream then heats up and evaporates. Then, that water makes a cloud. Then, the cloud condensates which makes it rain. This rain runs through the soil and rocks, downhill back to the stream. In the arctic, the rain flows down mountains, usually back into a sea or ocean.
In the Nitrogen Cycle, it starts with the animal, the polar bear (or cow in the illustration). The animal will defecate, which carries nitrogen into the soil as it is broken down by bacteria, and absorbed by the soil. Then, denitrifying bacteria will release the nitrogen into the air. After that, plants absorb the nitrogen, and the animal eats the plant, starting the cycle over.
In the Carbon cycle, dead marine life goes into the soil, and becomes a fossil. We mine out the fossils for fossil fuels, then burn it, releasing carbon into the atmosphere. Also, plant respiration, human respiration, animal respiration, and deforestation emits Carbon. The Carbon in the atmosphere is absorbed by oceanic plants and land plants, and also is breathed by humans and animals.
In the Phosphorus cycle, Phosphorus in the soil are absorbed by plant cells. The plants get eaten by animals, which defecate into the soil. Then bacteria and fungi break down the feces and the soil absorbs the remnants.
