D) Decay

Answer 1

denitrifying bacteria

Answer 2

One of the ways in which the nitrogen of atmosphere is converted into nitrate for plants is by the action of

B. Lightening

• Nitrogen in the atmospheric form cannot be used for chemical processes by almost all organisms.
• Thus, atmospheric nitrogen needs to be converted to usable forms such that plants and other organisms can use it.
• Lightening changes the atmospheric nitrogen into nitrates and ammonia as they are more readily absorbed by plants and organisms.
• These substances namely nitrates and ammonia enter the soil along with rainfall.
• Thus, lightening is one of the ways to fix atmospheric nitrogen into more usable forms.
