Differentiate between an upright and inverted pyramid.

Upright pyramid

1.     Producers are more in numbers than the herbivores and herbivores more in number than carnivores.

2.     Pyramid of energy is  always upright.

Energy at lower  trophic level is more than that in the higher level.

Inverted pyramid

1.     Pyramid of biomass  in a sea is inverted as the biomass of consumers  (Fish) is more than that of producers (phytoplanktons).

2.     Energy at lower trophic level is lesser than that of higher level.
