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

How to tell they’ve got it

Tick these off as you see them — no test required.

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

Try this together

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?
