An ecological pyramid (also trophic pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bio productivity at each trophic level in a given ecosystem.Biomass is the amount of living or organic matter present in an organism.Redirected from Energy pyramid). An energy pyramid is a presentation of the trophic levels in an ecosystem. Energy from the sun is transferred through the ecosystem by passing through various trophic levels.
The energy pyramid shows predators and prey. At the bottom, there is the most common and most available food/energy source. (This is usually sun or grass/plants). The next level up is a predator that eats the grass, or uses the sun. This would be an insect, most likely, such as a grasshopper that eats the plants. Or, this would be the grass that uses the sun's energy to make food. Anyways, the energy from one organism is transferred to the next organism. This chain continues on (bird eats grasshopper, snake eats bird, and hawk eats snake). Therefore, the hawk now had all of the energy of the sun, grass, grasshopper, bird, and snake. The hawk is the top predator, and would be at the top of the pryamid.
