Topic 1.10: Energy Flow and the 10% Rule
Learning Objective: ENG-1.C
Determine how the energy decreases as it flows through ecosystems.
Essential Knowledge: ENG-1.C.1
The 10% rule approximates that in the transfer of energy from one trophic level to the next, only about 10% of the energy is passed on.
Essential Knowledge: ENG-1.C.2
The loss of energy that occurs when energy moves from lower to higher trophic levels can be explained through the laws of thermodynamics.
