Explanation:

Water cycle is the process in which the water circulates in the earth’s surface and atmosphere in different forms by following the major process of evaporation and condensation.

Reservoir is the storage of air or water in the water or hydro-logical cycle. However, flux are the different processes that changes the form or state of water. Water is present in the form of liquid or snow or vapours in the environment.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
