 | An energy pyramid shows the progression of energy from the bottom tropic level, represented by grass, towards the top, represented by Artic Wolves. At the bottom, 100% of the energy is present. At the next level, only 10% of the original amount is left. The same is true from the second to the last level. At the highest trophic level, only 1% of the orginal amount is left. This occurs because energy is lost due to it being used in an organisms body, and released as heat. |
