Question

A student setup an experiment to study the growth of plants. The student used three (2)

potted plants with same amount of soil and additionally added manure in pot A,

fertiliser in pot B and left the pot C undisturbed. After 3 months, the student measured

the growth of each plant.



Pot Initial Growth(in cm) Final Growth(in cm)

A 10cm 25

B 10cm 35

C 10cm 18



The student again experimented and used the same soil for planting new plant. The table

shows the growth of each plant after 3 months.



Pot Initial Growth (in cm) Final Growth (in cm)

A 10cm 28

B 10cm 20

C 10cm 18



What can the student analyse from the experiment?​
