    The correct answer is: Phosphorus

      • Phosphorous is important for the growth and metabolism of plants
      • Phosphorous forms a part of the energy molecule called ATP
      • Soil contains phosphorous in the form of rocks
      • Phosphorous is artificially provided in the form of fertilizers, manures, etc
