Detailed explanation-1: -An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.

Detailed explanation-2: -A diagram that shows the transfer of energy in one line is a food chain. Energy can neither be created nor be destroyed it can only be transformed from one form to another. This conversion of energy is known Conservation law of energy. The flow of energy in one line can be represented by a food chain.

Detailed explanation-3: -Secondary and tertiary consumers, omnivores and carnivores, follow in the subsequent sections of the pyramid. At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat.

Detailed explanation-4: -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-5: -On average, only about 10% of the energy stored as biomass in one trophic level-e.g., primary producers-gets stored as biomass in the next trophic level-e.g., primary consumers. Put another way, net productivity usually drops by a factor of ten from one trophic level to the next.
