Biology · Secondary 4 · Medium · Pyramids of numbers and biomass
In a food chain, only about 10% of the energy at one trophic level is transferred to the next level.
Which statement best explains why this energy transfer is so low?
Which statement best explains why this energy transfer is so low?
- A large amount of energy is lost as heat during respiration and other activities.
- All of the energy eaten is converted into new biomass in the consumer.
- Consumers produce no faeces or urine, so no energy is lost as waste.
