Give a man a fish and hell eat for a day teach him to fish and get rid of him

This is very true but I don't see the question

Hope this is what you are asking for:

When discussing foreign aid, Nelson employed a modern version of the saying and called it a “Chinese proverb”: Foreign aid—“You give a poor man a fish and you feed him for a day. You teach him to fish and you give him an occupation that will feed him for a lifetime.

Hope this helps :))

The best way to tell its true color is to look at the minerals streak

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
