Detailed explanation-1: -The diagram that depicts the flow of energy, as well as the energy that is transferred from one feeding level to another, is called the energy pyramid.

Detailed explanation-2: -An ecological pyramid is a diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or food web.

Detailed explanation-3: -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.

Detailed explanation-4: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Detailed explanation-5: -A food chain is a simple diagram that shows one way energy flows through an ecosystem.
