Heterotrophic plants are less dependent on nitrogen obtained from nitrification since they receive some nitrite and nitrate through their parasitic or carnivorous nutritional modes.

Which of the following statements about nitrification is not true?a)N...
Nitrification and its statements:
Introduction:
Nitrification is a biological process in the nitrogen cycle that involves the oxidation (conversion) of ammonium ions (NH4+) to nitrite (NO2-) and further to nitrate (NO3-) by specific groups of bacteria. This process is of great importance as it converts ammonia, which is toxic to most organisms, into forms that can be readily utilized by plants.
Statement a:
Nitrobacter oxidizes nitrite to nitrate.
This statement is true. Nitrobacter is a genus of bacteria that carries out the oxidation of nitrite to nitrate. This process is an important step in nitrification.
Statement b:
Nitrosomonas and Nitrosococcus convert ammonium ions to nitrite.
This statement is also true. Nitrosomonas and Nitrosococcus are genera of bacteria that are responsible for the conversion of ammonium ions to nitrite in the nitrification process.
Statement c:
Nitrification reactions are energy-producing (exergonic) reactions.
This statement is true. The nitrification process is exergonic, meaning it releases energy. The oxidation reactions carried out by the nitrifying bacteria release energy that can be utilized by the organisms involved.
Statement d:
Heterotrophic plants are more directly dependent on the nitrifying bacteria for usable nitrogen than autotrophic plants.
This statement is not true. Heterotrophic plants obtain their nitrogen from organic compounds, while autotrophic plants (such as most green plants) can directly assimilate inorganic nitrogen from the soil. Therefore, autotrophic plants do not rely solely on nitrifying bacteria for usable nitrogen.
Conclusion:
In conclusion, statement d is not true. Heterotrophic plants are not more directly dependent on nitrifying bacteria for usable nitrogen compared to autotrophic plants. Autotrophic plants have the ability to directly assimilate inorganic nitrogen from the soil, whereas heterotrophic plants obtain their nitrogen from organic compounds.
