What do you mean by ecological energy pyramid?
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. As each animal is eaten, it goes to the top of the pyramid, showing that there are less and less predators. For example, there is more grass than hawks, right? hope this helps!
