So a river is designed to channel the flow of water, and the lightning bolt that comes out of a cloud channels the flow of electricity, and a leaf is designed to channel the flow of nutrients to the tree, sometimes even having to route around an obstacle, but to get that nutrition flowing.
Rijeka je dizajnirana da usmjerava tok vode, udar munje koja izlazi iz oblaka usmjerava tok elektriciteta, a list je dizajniran da usmjerava tok nutrijenata u stablu, ponekad čak i obilazeći prepreke, no u svrhu protoka nutrijenata.
