CAIE IGCSE Biology 19.2.9 Decomposer as an organism that gets
Practise defining decomposers and recognising them from evidence about dead or waste organic material in nutrient and biomass contexts.
How this is tested
- define a decomposer as an organism gaining energy from dead or waste organic material
- identify decomposers from descriptions involving waste from all trophic levels
- interpret biomass-pyramid evidence to decide where detritivores feed
