Is this true or false? Approximately 10 percent of the energy is destroyed at each step of the energy pyramid?

Energy is neither created or destroyed. It just changes form. Short and simple answer.Is this true or false? Approximately 10 percent of the energy is destroyed at each step of the energy pyramid?
This is a not a physics question.


False. 10% goes on. It is 90% that is ';destroyed';. Of course energy is not really created or destroyed - what this statement means is that an organism uses 90% of the food energy it takes in in order to maintain its vital processes and to move around; it only stores 10% of this energy in its tissues, so only 10% is available for predators to consume.
