Cellular respiration releases energy from food molecules for use by organisms. As energy transfers between trophic levels are not 100% efficient, a significant amount of energy is lost at each level. This limits the number of trophic levels in an ecosystem, since there is a decrease in available energy as you move up the food chain.
Ecological pyramids show the relative amount of energy or biomass stored at each trophic level in a food web. They illustrate the decrease in energy or biomass as it moves up the trophic levels due to inefficiencies in energy transfer.
The pyramid of energy always remains upright because energy diminishes as it moves up trophic levels in an ecosystem. This is because energy is lost as heat during each transfer between trophic levels, leading to a decrease in available energy for higher trophic levels.
Loss of energy in the food chain limits the amount of energy available to higher trophic levels, such as apex predators, resulting in a decrease in biomass at each successive trophic level. This loss of energy ultimately constrains the overall biomass and productivity of an ecosystem.
The inefficiency of energy transfer from one trophic level to the next is primarily responsible for limiting the number of trophic levels in most ecosystems. As energy is transferred up the food chain, a significant amount is lost as heat, resulting in less energy available to support higher trophic levels. This limits the number of trophic levels that can be sustained in an ecosystem.
Only around 10% of energy is transferred between trophic levels because energy is lost through metabolism, heat production, and waste. Each time energy is transferred between trophic levels, some of it is used for the organism's own needs, which results in a decrease in the amount of energy available for the next trophic level.
As you climb trophic levels the general amount of energy lost is 90% so you get about 1/10 of the energy that was consumed by the animal per trophic level.

Different trophic levels have different amounts of energy because energy is lost as it moves up the food chain. Organisms at higher trophic levels must consume a larger amount of lower trophic level organisms to obtain enough energy to sustain themselves. This inefficiency in energy transfer limits the amount of energy available at each trophic level.
Loss of energy in the food chain limits the amount of energy available to higher trophic levels, such as apex predators, resulting in a decrease in biomass at each successive trophic level. This loss of energy ultimately constrains the overall biomass and productivity of an ecosystem.
Energy transfer between trophic levels is not very efficient, leading to a loss of energy as it moves up the food chain. This limits the number of trophic levels that can be supported in a food web. Additionally, with each higher trophic level, there is a decrease in available energy and biomass, making it difficult to sustain more than 4 trophic levels.

Energy decreases as you move up the energy pyramid due to energy loss at each trophic level through respiration, heat loss, and incomplete digestion. Organisms at higher trophic levels must consume more food to meet their energy needs, resulting in less energy transfer to the next trophic level.
Energy is lost between trophic levels due to inefficiencies in energy transfer as organisms consume and metabolize food. Each trophic level only retains about 10% of the energy from the previous level, with the rest being lost as heat or used for respiration and other metabolic processes. This results in a decrease in energy available to higher trophic levels in the food chain.
