    • Food Energy Pyramids
      As energy passes to a higher tropic level, approximately 90% of the useful energy is lost. High tropic levels contain less energy and fewer organisms than lower levels. At each tropic level in a food chain, energy is used by the organisms at that level to maintain their own life process. Because of the 2nd law of energy, some energy is lost to the surroundings as heat. it is estimated that in going from one tropic level to the next, about 90 % of the energy is lost.
