How are the processes of the water cycle essential to an unpolluted biosphere?

Explanation:

if things on earth like dead animals or polluted chemicals in the air can affect the biosphere so keeping the stages of the water cycle safe and clean are essential to keeping the biosphere unpolluted. because  Evaporation & transpiration distill water naturally, it filters out minerals and pollutants.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
