Assertion: In most ecosystem , all the pyramids, of number, energy and biomass are upright.
Reason: In a food chain producers are more in number and biomass than the herbivores, and herbivores are more in number and biomass and carnivores.

Producers are generally more in number or biomass than herbivores in an upright pyramid. c. Herbivores are less in number and biomass than carnivores in an inverted pyramid. d. Energy content is higher at a lower trophic level than that at a higher trophic level.

Which of the following statement/s regarding ecological pyramid is/are wrong? I. In most ecosystem, all the pyramids, of number, of energy and biomass are upright. II. Each trophic level has a certain mass of living material at a particular time called as the standing crop. III. The pyramid of biomass in sea is generally upright because the biomass of fishes far lower that of phytoplankton. IV. Pyramid of energy is always upright, can never be inverted. V. Energy at a lower trophic level is always less than at a higher level.
