Question

Match the given nutrients with their appropriate uses.

$\begin{array}{cc}\text{Nutrients}& \text{Uses}\\ \text{(i) Potassium}& \text{(a) helps roots to penetrate into the soil}\\ \text{(ii) Phosphorus}& \text{(b) induces new leaves, flowers}\\ \text{(iii) Nitrogen}& \text{(c) provides resistance against pest}\end{array}$

• A. i - b, ii - a, iii - c
• B. i - a, ii - c, iii - b
• C. i- c, ii -b, iii - a
• D. i - c, ii - a, iii - b

Answer 1

The correct option is D i - c, ii - a, iii - b

$\bullet$ Soil is the source of different nutrients for the plants. Among these they require NPK (Nitrogen, Phosphorous, Potassium) in larger quantities and are called macronutrients.

$\bullet$ Given below are the uses of these nutrients:
$\begin{array}{cc}\text{Nutrients}& \text{Uses}\\ \text{Potassium}& \text{provides resistance against pest}\\ \text{Phosphorus}& \text{helps roots to penetrate into the soil}\\ \text{Nitrogen}& \text{induces new leaves, flowers}\end{array}$
