Plants take nitrogen in the form of nitrates.

Fruit growing have following economic and
nutritional advantages. High productivity: High
yield per unit area: From a unit area of land more
yield is realized from fruit crops than any of the
agronomic crops. The average yields of Papaya,
Banana and Grapes are 10 to 15 times more that of agronomic crops.
The short answer is that cells respond to the chemical environment in which they find themselves.

Explanation:
During respiration, members of the animal kingdom use oxygen and then release carbon dioxide as a waste gas.
Members of the animal kingdom have a respiratory system that is composed of muscles, and airways that functions together to transport air into lungs, and the oxygen is used by cells. Carbon dioxide is also transported away from the cells as a waste gas. Respiration relies on other systems, such as the circulatory system, to transport oxygen and carbon dioxide to and from cells.
