Hey!!
Here's your answer....
ACTIVITY:-
Take some gram seeds and germinate them.
Put those seeds in 3 cups filled with soil in equally distributed amount.
Mark these cups A,B,C respectively.
In cup A...mix a little amount of cow dung.
In cup B...mix a little amount of urea.
In cup C...do not mix anything in it.
Regularly pour same amount of water in the 3 cups.
After 10 days observe those 3 cups carefully.
OBSERVATION:-
You will see that the plants are grown in every cup.
Cup B will be grown healthier than other 2 because with the help of urea and then cup A will be seen little healthier than cup C because cow dung was added and cup C will less healthier than other 2 because anything was added to it's soil.
So, this activity shows that.... with the help of fertilizers a plant can be grown more healthier than ever.
Hope it will help you!!!
