Detailed explanation-1: -An energy pyramid, also known as a trophic or ecological pyramid, is a graphical representation of the energy found within the trophic levels of an ecosystem. The bottom and largest level of the pyramid is the producers and contains the largest amount of energy.

Detailed explanation-2: -BACKGROUND: An energy pyramid illustrates how energy flows through an ecosystem. By showing the trophic (feeding) levels of the ecosystem, students can easily visualize how energy is transferred from producers to consumers.

Detailed explanation-3: -An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain. The pyramid base contains producers-organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers.

Detailed explanation-4: -An energy pyramid shows the flow of energy at each trophic level in an ecosystem. A pyramid shape is used because energy is lost at each trophic level when organisms use it up.

Detailed explanation-5: -Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
