To protect and provide support for the cell
1.Water evaporates in the presence of sunlight.
(hydrosphere)
2.Volcanoes release a large amount of gases and other matter during eruption.
(lithosphere)
3.Lightning causes nitrogen molecules to be split and carried by rain.
(hydrosphere)
4.Plants release water vapor through their leaves during transpiration.
(biosphere)
Hope this helps!
