The given statement is False
Bleach such as chlorine when mixed in fertilizers acts as a killing agent for plants .The bleach runoff is not affected by the fertilizers containing bleach as they do not kill the Aquatic flora. Marine bleaching is caused due to high temperature of water not because of the fertilizers. In marine bleaching the coral will expel algae when the temperature of water is high. These results in discoloration of corals making them white and they can survive in this condition. This proves that the bleaching inside the marine system is because of high temperature not because of runoff.
Explanation:
Denitrification is basically a biochemical phenomenon where nitrate is used by the bacteria living in the soil for the process of their respiration instead of using Oxygen from the air, consequently, the nitrates are converted into nitrous oxide and nitrogen gas. The process of denitrification is accelerated mostly in the wet and warm soil where there is lot of nitrate available.
This process is exhibited by Alkaligenes, Pseudomonas and Bacillus etc. Most of the bacteria involved in this process are facultative aerobially heterophs who has the ability of switching to denitrification from normal respiration when they find that the normal oxygen is running out.
