Photosynthesis is a process of food and energy production by autotrophs. Water and carbon dioxide in the presence of sunlight gives oxygen and sugar.
Photosynthesis is a biochemical reaction that uses organic and inorganic compounds and converts the molecules with the help of biological organs and substances.
The reactant of the process includes atmospheric water vapours, carbon dioxide and the heat and energy from the sun. These reactants are used by plants and some other organisms.
The organism utilizes the reactants and produces molecules of sugar like glucose and by-product oxygen. These molecules are necessary for the metabolic and respiratory processes.
Therefore, option B. [tex]\rm sunlight + water + carbon\; dioxide \rightarrow oxygen + sugar[/tex] is the correct equation that describes photosynthesis.
