Vedclass · Answer

(B) In a marine ecosystem,the total biomass of primary producers (phytoplankton) is much lower than that of consumers (zooplankton and fish) because they have a short lifespan and are consumed rapidly. Therefore,the pyramid of biomass in the sea is generally inverted. The statement in option $B$ that 'the pyramid of biomass in the sea is generally upright' is incorrect. The pyramid of energy is always upright because energy is lost at each trophic level during the flow of energy. In a grassland ecosystem,the pyramid of numbers is upright because the number of producers is significantly higher than the number of consumers.

Which of the following statements is not correct?

Reason : Number of organisms at any trophic level depends upon the availability of organisms which serve as food at the lower level.

In a pyramid of biomass, $P$ is at the highest trophic level, $Q$ is at the second trophic level, and $R$ is at the lowest trophic level. Identify $P, Q,$ and $R$.

Give scientific reasons: Energy pyramids are never inverted.
