Producers are found at the bottom level of the energy pyramid. They are organisms that can photosynthesize, creating energy from sunlight, and form the foundation of the food chain by providing energy to other organisms.
A diagram that shows an ecosystem's loss of energy at each level of the food chain is called an energy pyramid. It depicts the decrease in available energy as it moves up trophic levels due to the inefficiency of energy transfer between organisms. Typically, only about 10% of energy is passed on to the next trophic level, with the rest being lost as heat through metabolic processes.
The trophic levels show which organisms are at each level of the energy pyramid. The pyramid is shaped exactly as a pyramid. The lowest level contains the most energy and the most in number and variation of species. The next level only has 10% of the first levels' energy and fewer species. The amount of energy in the first level determines the number of levels possible. The tropical rain forest has the most levels (as many as 4) and a desert has the fewest (as few as 2).

A pyramid of energy represents the flow of energy through different trophic levels in an ecosystem. It demonstrates the decrease in available energy as it moves up the food chain due to energy loss through metabolism and heat transfer. The pyramid shape indicates that each higher trophic level has less energy available than the one below it.
The model is called an energy pyramid. It illustrates the flow of energy through a food chain, showing how energy decreases as it moves from one trophic level to another.
Producers have the most energy at the pyramid level because they manufacture food from inorganic raw materials.

The most energy in an energy pyramid is typically found at the base, with the primary producers (such as plants) converting sunlight into energy through photosynthesis. Each level up the pyramid contains less energy as it is transferred through the food chain.

The level on the energy pyramid with the most biomass is usually the bottom level, which consists of producers like plants and algae. These organisms have the highest biomass because they are able to convert the energy from the sun into food through photosynthesis.
The energy pyramid shows how the amount of useful energy, food, decreases as organisms in that level use it. Even though a lot of energy may be taken in at any level, more energy in the form of food that is available to the next level, is stored on the bottom level and decreases at each level as you move to the top of the pyramid. Thus, there is much less energy to support organisms at the top, so there are fewer in most communities.
