A visual display of the decrease in available energy in an ecosystem at each trophic level is called an energy pyramid. In this pyramid, the energy stored by organisms at each level is approximately one-tenth of that at the level below it, illustrating the loss of energy as it moves through the food chain. This concept highlights the inefficiency of energy transfer between trophic levels, emphasizing that only a small fraction of energy is passed on to the next level.
The trophic level of herbivores generally contains more energy than that of carnivores. This is because energy is lost at each trophic level due to metabolic processes, with only about 10% of the energy from one level being transferred to the next. Since herbivores are primary consumers that directly consume plants (producers), they have access to the energy stored in plants, whereas carnivores (secondary consumers) rely on herbivores for their energy, resulting in a lower energy availability at their level.
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.
Around 90% of the total solar energy is used by the producers for food manufacture, growth, reproduction, and survival. The solar energy that is not stored by primary producers is lost as heat.
At the base of the food chains lies the primary producers. Primary producers are principally green plants and certain bacteria. They convert solar energy into organic energy. Above the primary producers are the consumers who ingest live plants or the prey of others. Decomposers, such as, bacteria, molds, and fungi make use of energy stored in already dead plant and animal tissues.

This is because organisms use much of the energy that they consume for life processes, such as respiration, movement, and reproduction.
This block represents the trophic level with the most stored energy.

The Ten percent law for the transfer of energy from one trophic level to the next was introduced by Lindeman (1942). According to this law, during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the of energy from organic matter is stored as flesh. The remaining is lost during transfer, broken down in respiration, or lost to incomplete digestion by higher trophic levels.
The stored energy that does not advance from one trophic level of the food chain to the next either disappears into the air or is used by the organism containing it.
The level containing the most stored energy is the primary producer level. This is because primary producers, like plants, convert sunlight into chemical energy through photosynthesis, which is then passed on to consumers at higher trophic levels.
The greatest amount of energy stored in an ecosystem is found in producers, such as plants, which convert sunlight into chemical energy through photosynthesis. This energy is then transferred through the food chain to herbivores and to carnivores, with energy decreasing at each trophic level due to metabolic losses.
