Question - Among the four living organisms R is present at the first trophic level while P is a secondary consumer because it depends on Q for its food and S is a tertiary consumer .Then which of the following options is correct for P, Q, R, S?

A) P-Plant products, Q- Snake, R - Lion, S-Hawk

B) P -Frog, Q-Grasshopper, R- Plant products, S-Snake

C) P-Grasshopper, Q-Snake, R-Plant products, S-Frog

D) P-Snake, Q -Plant products, R- Frog, S-Grasshopper

Answer - Correct option is B) P -Frog, Q-Grasshopper, R- Plant products, S-Snake

• As stated in question, R is present at first trophic level. This implies it is a producer which are only plant products.

• P is stated as secondary consumer dependent over Q. This makes Q as a primary consumer of producer and among the given options Grasshopper is dependent on plant products.

• Grasshopper is diet of frog and hence frog will be P.

• S is a tertiary consumer and hence will eat P as food. Snake eats frogs and hence it will be S.
