A chemical or natural substance used for the fertility increase of soil and land is fertilizer.

• In agriculture fertilizer helps to increase the growth rate of the plants and food production.
• but when the use of fertilizer increase beyond the limit the chemicals in it will affect the environment very badly.
• When the fertilizer comes in contact with the water then the chemicals in the fertilizer enable the growth of the microorganism.
• The dissolve oxygen creation will be affected by this microorganism growth.
• Fish and other creatures that live in water will suffocate on the reduced amount of dissolved oxygen quantity in water.
