2. Why does a plant grown in waterlogged soil show nitrate deficiency?

3. Denitification takes place. Active transport cannot take place. Nitrate ions are soluble.

4. Instructions In each rain cloud there is a partial explanation for why plants grown in waterlogged conditions show nitrate deficiency. Can you complete these explanations by providing more detail. The explanation must be full and detailed.
