Explain the 10% rule and how energy flows through an ecosystem
The 10% rule states that only 10% of energy is transferred between trophic levels. 90% of energy is lost as heat to the environment. Energy begins with the sun which is then absorbed and changed into sugars by producers. Primary consumers eat producers to gain energy. Secondary consumers eat primary consumes to gain energy. When living organisms die, decomposers break them down to gain energy and act as natural fertilizer for new producers
