It is essential to maintaining homeostasis in every organism. It contributes to the fitness of the environment. Its movement within and between ecosystems transfers other materials in several biogeochemical cycles. Most of the water cycle occurs between the oceans and the atmosphere. Solar energy results in evaporation from the oceans.
Water vapor rises, cools, and falls as precipitation.
The water cycle differs from other cycles in that it occurs primarily due to physical processes, not chemical processes. The carbon cycle In the carbon cycle, photosynthesis and cellular respiration form a link between the atmosphere and terrestrial environments. Some of this becomes a carbon source for consumers, and respiration returns CO 2 to the atmosphere. Carbon recycles relatively quickly. Carbon loss by photosynthesis is balanced by carbon release during respiration .
