Give the diagrammatic representation of nitrogen cycle witj explanation.
Answers
Answer:
The nitrogen cycle explains how nitrogen moves through the soil, atmosphere, bacteria, plants, and animals on Earth. The nitrogen cycle is special because, despite making up around 78 percent of the air in the atmosphere, nitrogen cannot be used directly by animals or plants without first being transformed into other chemicals.
Explanation:
The nitrogen cycle refers to the process by which nitrogen from the atmosphere is taken up by soil and living things before being returned to the atmosphere.
a) Fertilizers, animal and plant waste, and other substances add nitrogen to the soil. The nitrogen is changed by soil bacteria into ammonium and nitrate, which are then absorbed by plants through a process called nitrogen fixation.
b) Ammonification: Ammonification is the process of creating ammonia from organic molecules. Proteins, amino acids, and other nitrogen-containing substances in decomposing and waste organic matter are broken down by a variety of microbes during a process called ammonification to produce ammonia.
c) Nitrification: This is the process of turning ammonia into nitrites (NO2-) and eventually nitrates (NO3-). Specialized microorganisms do this function in the environment on a natural basis.
d) Nitrate is biologically converted to nitrogen gas, nitric oxide, or nitrous oxide through denitrification. Since these substances are gaseous and not easily accessible for microbial development, they are frequently released into the atmosphere. Since nitrogen gas makes up more than 78 percent of the gases in the atmosphere, releasing N2 into the environment is safe.
