Answer

Brief Explanations:

  • Q1: Plants absorb nitrogen mainly in the form of nitrates.
  • Q2: Excess nitrogen can cause eutrophication in water - bodies.
  • Q3: Nitrate leaving soil in drainage water is called leaching.
  • Q4: The correct sequence of the nitrogen - cycle is fixation, assimilation, ammonification, nitrification, denitrification.

Answer:

Q1. B. Nitrates Q2. C. Overly enrich bodies of water, resulting in Eutrophication Q3. A. Leaching Q4. A. fixation, ammonification, assimilation, denitrification, nitrification
