Given below are two statements one labelled as Assertion (A) and the other labelled as Reason (R).
Assertion (A): Earthworms are not good for agriculture.
Reason (R): Earthworms break down the soil into fine particles and make it soft.
Code:
(A) and (R) both are correct, and (R) is the correct explanation of
(A).
Correct Answer:
(D)
is wrong, but (R) is true.
Earthworms give a special contribution in the formation of soil and increase its productivity. They are called the 'ecosystem engineer'. They construct pores in the soil through which water and oxygen enters and carbon dioxide come out. The wastes of the earthworms are important for the productivity of the soil. They convert the soil into fi ne particles and make it soft. They act as decomposers. Hence, it is evident that assertion is wrong and reason is correct.
