Energy Loss Between Levels
Explain how energy is transferred between trophic levels in a food chain, why energy is lost at each stage, and use pyramids of biomass/numbers to represent this
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
If your child was asked why there are so many more plants than foxes in a field, could they explain how energy gets lost at every step of a food chain and what that means for the size of each population?

Check understanding
- Explains that only about 10% of energy passes from one trophic level to the next
- Constructs a pyramid of biomass from data and explains its shape
- Identifies where energy is lost at each trophic level (heat, movement, waste)
- Explains why food chains rarely have more than five trophic levels
