Who first explain the theory of cultural diffusion answers?

Diffusion is the process of passively(without loss of energy) movement of any substance from higher concentration to the lower concentration of that substance.

in amoeba diffusion depends upon the salt concentration inside and out side of its body. in plant root cell diffusion depends upon mineral concentration inside and out side of root cell. And in alveoli diffusion depends on CO2 and O2 concentration inside and out side of alveolar sack.

I HOPED THIS HELPED :)
