Question

Which one of the following statements for
pyramid of energy is incorrect, whereas the
remaining three are correct ?
(a) Its base is broad
(b) It shows energy content of different trophic
level organisms
(c) It is inverted in shape
(d) It is upright in shape

Answer 1

Pyramid of energy is always upright and can never be inverted, because when energy flows from a trophic level to the next trophic level some energy is always lost as heat at each step. 

Answer 2

The statement - It is inverted in shape is incorrect.

* Energy pyramid is used to represent the biomass at every trophic level in an ecosystem.

* 10℅ of the energy in a trophic level is transferred to the next trophic level. Hence, as trophic level increases, the pyramid becomes narrower and is hence always upright.

* The pyramids begin with producers and gradually proceed on to consumers. The top of the pyramid forms the highest level of a pyramid.
