Energy Pyramid
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).

There are always more prey organisms than producers in a community. Murshedur Rahman
Those at the top of the food pyramid contain consumers with the smallest number and therefore, with the least total biomass compared to the layers below them.
An energy pyramid portrays the flow of energy by displaying the plants at the bottom, who get the most energy from the sun, and then gradually moving up to herbivores as it shows the transferal of energy from the plants to the herbivores and how the amount of energy received is significantly less than the original amount. The pyramid then shows how energy is passed from carnivore to carnivore and decreases in amount each time. The pyramid gets smaller as you reach the top of the food chain because not as much energy can be acquired by eating an animal that has eaten another animal that has eaten a plant that received energy from the sun. The energy decreases as it is passed from one creature to the next and the pyramid depicts this as it gets smaller toward the top. Helpful?
Producers have the most energy at the pyramid level because they manufacture food from inorganic raw materials.
