Q. Consider the following statements I. The pyramid of biomass is inverted in a pond ecosystem II. Pyramid of energy is never inverted III. Pyramid of number is inverted in a tree ecosystem IV. Pyramid of biomass in forest ecosystem is upright Which of the statements given above are correct?
A) I, II and III
B) I, III and IV
C) II, III and IV
D) I, II, III and IV
Explanation
The pyramid of biomass is inverted in a pond ecosystem, where a large fish eats upon a large number of small phytoplanktons The pyramid of energy is always upright because the flow energy is unidirectional Pyramid of number is inverted in a tree ecosystem. In case of a tree, the number of producers is less compared to consumers Pyramid of biomass is upright in case of a tree which supports a large number of small birds
