Given below are two statements: one is labelled Assertion(A) and other is labelled Reason(R).

Assertion(A): Saprophytes are not given a place in the ecological pyramids.

Reason(R): They do not play a vital role in the ecosystem.

In the light of above statements, choose the correct answer from the options given below.

Saprotrophs are considered critical to decomposition and nutrient cycling. They include fungi, certain bacteria, water molds, etc. They are decomposers which secrete digestive enzymes that breakdown dead and waste materials into simple, inorganic materials, which are subsequently absorbed by them. Thus, they play a vital role in the ecosystem. But, they are not given any place in ecological pyramids.
