    Question

    Rice plants have a specific preference for the form of

    nitrogen they uptake. Which form is most efficiently absorbed by rice under submerged conditions, and why is it preferred?
    A Nitrate form (NO₃⁻), due to its high solubility Correct Answer Incorrect Answer
    B Ammonical form (NH₄⁺), because it is more stable in anaerobic soils Correct Answer Incorrect Answer
    C Urea form (CO(NH₂)₂), for its slow-release properties Correct Answer Incorrect Answer
    D Nitrite form (NO₂⁻), due to its rapid absorption Correct Answer Incorrect Answer
    E Elemental nitrogen, for direct assimilation by roots Correct Answer Incorrect Answer

    Solution

    Rice absorbs nitrogen more efficiently in the ammonical form (NH₄⁺) under submerged conditions, as it remains stable and readily available in anaerobic environments.
