fertilizers
Explanation:
Plants use nitrates as a supply of nitrogen, which is needed to make proteins for healthy growth. Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces.

The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus. <span />
Answer:
CO2 and H2O are the reactants in the given reaction
Explanation:
The reaction that is written in the question is the general equation of photosynthesis.
In this reaction the carbon di oxide reacts with water to form glucose ,oxygen and water.The overall reaction is given below
6CO2+12H2O= C6H12O6+6O2+6H2O
carbon di oxide(CO2) and water(H2O) act as reactant in the above reaction.
