<span>the soil</span>
The nitrogen used by most plants is derived from soil.
Nitrogen is an important element. It is needed by organisms to produce amino acids
Nitrogen is made usable for plants by bacteria which change nitrogen to ammonium.
Ammonium gets changed to nitrates by bacteria in a process called nitrification, which takes place in soil.
Nitrates is the form that plants can absorb. They absorb it through their roots and use it to make amino acids, nucleic acid and chlorophyll.
The phloem is essential for transporting sugars the plant has made to other areas of the plant, this is necessary as some areas of the plant cannot perform photosynthesis or perform it at a much slower rate. E.g. the roots can't perform photosynthesis to get the sugars it needs because they aren't exposed to light, but they still need energy to function and without sugar transport by the phloem they would not get this so areas of the plant would die

GAS EXCHANGE: the intake of Oxygen and the expulsion of Carbon dioxide. In the capillaries of the alveoli, oxygen travels due to the concentration gradient into those capillaries. Carbon dioxide is then expelled from those capillaries.
RESPIRATORY MEDIUM: is air for animals and water for fish. It is basically the substance through with living animals receive their oxygen.
RESPIRATORY SURFACE: is where the gaseous exchange takes place. The oxygen and carbon dioxide move across the respiratory surface entirely by diffusion.
