Question
While nutrients cycle through environments, energy flows through an environment in one direction. This flow of energy is often shown with an energy pyramid, such as the one below.Trophic Levels by Saric (CC BY-SA 3.0)Which of the following correctly states the percentage of energy lost between each trophic level on the energy pyramid and what that energy is lost as?Elimination ToolSelect one answerA90%90%, exercise.B10%10%, exercise.C90%90%, heat.D10%10%, heat.
Solution
The correct answer is C90%90%, heat. This is because as energy moves up the trophic levels in an ecosystem, approximately 90% of the energy is lost, primarily as heat. This is a result of the second law of thermodynamics, which states that whenever energy is transferred or transformed, a significant portion is lost as heat.
