Given below are two statements: Statement I: Ecological pyramids cannot accurately depict the trophic position of an organism like a sparrow, which feeds on both seeds and insects. Statement II: The construction of ecological pyramids is based on the assumption that a complex food web operates in the ecosystem. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

It does not accommodate the complexities of a
