Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.

If a struggle for existence is apparent, natural selection occurs because all of the weak/unfit/unadapted ones die.
