As we discussed earlier, plants get their food with the help of photosynthesis. By consuming solar or light energy, they can synthesize nutrients from breakdown of CO2 and H2O. For photosynthesis, both light reaction and dark reaction performed by plants. Light reactions are those reactions, that are carried out in presence of light and those of dark reactions are carried out in night that means within dark phase. As we can observe in diagram.
The major components of photosynthesis are water, air, light and minor components are minerals. Plants trap light energy, this light is received by chlorophyll which is present in leaf of the plant. With the help of this light energy 6 molecules of CO2 and 6 molecules of H2O are split into 6 carbon compound sugar called as glucose [C6H12O6]. Similarly light energy get converted into chemical energy.
The nutrients required by plants are inorganic nutrients. The inorganic nutrients means simpler form of salts. These nutrients plants absorbed from the soil, therefore for the growth of plant quality of soil is important. The inorganic nutrients such as Nitrogen, Copper, Magnesium, Potassium, Phosphorus, Iron, Cobalt etc.
How these nutrients present in soil ?
These inorganic nutrients are formed in soil, due to process of decomposition of living organic matter, along with that various types of microorganism are present in soil, they also provide nutrients, and increases the quality of soil. The earthworm also contains the millions of microorganism, whereas breakdown of rocky material on earth also produces various nutrients.
