Pyramid of energy- Definition, Levels, Importance, Examples

The pyramid of energy is a graphical representation that shows energy accumulation patterns at different tropical levels in an ecosystem.

• The energy flow moves from the bottom to up through the layers of the energy pyramid. Energy is higher at the bottom of the pyramid but gradually reduced as energy is used up by the organism at each level.
• It is one of the types of three ecological pyramids along with the pyramid of numbers and the pyramid of biomass.
•  The pyramid of energy represents the energy flows in the ecosystem. It helps quantify energy transfer from one organism to another along a food chain.
• The number and weight of organisms at any level depending on the rate at which food is being produced rather than the amount of fixed energy present at any one time in the level just below.
• The pyramid shape is used due to how energy is utilized and lost at each tropic level when organisms use it up.
