What Does a Tree Live on?

A tree, unlike an animal, neither drinks milk, nor eats food, so what does it live on? It lives on water and fertilizer. The latter consists of various nutrients-mainly nitrogen, phosphorus and potassium. Each nutrient has a specific function -nitrogen helps a tree develop luxuriant growth; phosphorus makes fruits ripen earlier and potassium helps the trunk grow thick. They all dissolve in water and are selectively assimilated by plant roots according to their needs. In their leaves, trees synthesize carbohydrate from the absorded moisture and carborn dioxide from the effect of sunshine Thus the assimilated nutrients and synthetized carbohydrate keep trees growing
