Less biomass is gained in each trophic level
Explanation:
Animals use energy for growth, movement and keeping a constant body temperature. This means that less biomass is passed on to the next trophic level.
When animals egest , biomass is lost so less biomass and energy is passed on to the next trophic level.
This means that a food chain with many trophic levels will have very little biomass and energy passed on to the top consumer.
A food chain with few trophic levels will have a lot more energy passed on to the top consumer.
