Define the pyramid of biomass.

Position of herbivores in the pyramid of biomass is

[A] : The pyramid of biomass indicates the decrease or the gradual reduction in biomass at each trophic level from base to apex . [R] : In case of parasites , the pyramid of biomass is inverted .

(a) ''The pyramid of energy is always upright.' Explain. (b) Explain with the help of labelled diagrams, the difference between an upright pyramid of biomass and an inverted pyramid of biomass.

Which of the following correctly represent the pyramid of biomass in aquatic ecosystem ?

In an open ocean, the biomass of primary producers (microscopic algae) is often lower than the biomass of higher trophic levels (zooplanktons and fish), as illustrated below by an inverted pyramid of biomass. How can there be enough food in an open ocean to support the higher trophic levels?

Draw a 'pyramid of numbers' of a situation where a large population of insects feed upon a very big tree. The insects in turn, are eaten by small birds which in turn are fed upon by big birds. (b) Differentiate giving reason, between the pyramid of biomass of the above situation and the pyramid of numbers that you have drawn.

In grassland ecosystem, the pyramid of biomass is

An inverted pyramid of number and an inverted pyramid of biomass are respectively seen in:

An inverted pyramid of biomass can be found in which ecosystem
