Question

The given picture illustrates the use of ­­­­­­­­_________________ by plant.

  1. Inorganic fertilizer
  2. Biofertilizer
  3. Insecticide
  4. Herbicide

Hint:

Bacteria acts as biofertilizer for the plants

The correct answer is: Biofertilizer


    • The given picture shows uptake of phosphorus by the roots of plants 
    • The phosphorus is first converted from non absorbable form to the absorbable by the bacteria 
    • The bacteria , fungi etc are biofertilizers
    • These are phosphate solubilising bacteria
    • It is then absorbed by the root system
