Question

Why is the pyramid of energy always upright?

Answer 1

Pyramid of energy:

1. A graphical representation of the biomass or bioproductivity at each trophic level in a given ecosystem is called an ecological pyramid.
2. The energy pyramid is always upright because energy is constantly lost as heat when it travels from one trophic level to the next.
3. This heat escapes into the atmosphere and is never returned to the sun.
4. Therefore, at any point in time, a particular trophic level will have less energy compared to the previous trophic level.
