Photosynthesis is defined as the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Nitrogen is the chemical element of atomic number 7, a colourless, odourless unreactive gas that forms about 78 per cent of the earth's atmosphere.
Respiration is a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide.
