Question

(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.

Answer 1

Pyramid of energy.

Explanation:

• When the energy flows from one trophic level to the next trophic level , in each step some energy is always lost as heat. This suggest that pyramid of energy is upright always.

• This heat goes to the atmosphere and never comes back to the sun.
• Difference between an Upright pyramid of biomass and an Inverted pyramid of biomass is:
• 1. The number and biomass of the producer level is the highest in upright pyramid.
• 2. the number and biomass of the producer level is the lowest in inverted pyramid.
