How is water cycled throughout living and nonliving reservoirs on earth?

Water cycle or the hydrological cycle is a classic example of biogeochemical cycle involving the circulation of water between the atmosphere and the earth.

Water is circulated between the earth and the atmosphere by the processes of evaporation, condensation and precipitation. Evaporation is the transformation of water into water vapour from the water bodies and the plants through transpiration. The water vapour is then transformed into liquid water droplets in the air creating clouds and fog. The water droplets reach the earth through the process of precipitation in the form of rain. This cycle of evaporation, condensation and precipitation continues as a cycle called the hydrological cycle.

the cell theory states that all living things including animals, as well as plants, are made of cells.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
