The correct response is: Secondary and tertiary consumers have to consume a lot more food to support themselves, so there are fewer of them.
This is because, at each trophic level, energy is lost as heat and through metabolic processes. As a result, there is less energy available to support higher trophic levels, leading to fewer organisms that can be sustained.
