C4.2.12—Energy reductions Topic Practice
Practise explaining reduced energy transfer between trophic levels and using data on feed conversion, biomass gain and edible mass.
How this is tested
- explain energy losses through respiration, heat, movement, wastes and uneaten material
- calculate or compare feed conversion ratios to judge biomass or protein production efficiency
- apply food-chain length and trophic-level differences to explain varied transfer efficiency
