Why is there less biomass at the top of the energy pyramid?(1 point)

Responses

Secondary and tertiary consumers have bigger ranges, so there are fewer of them because they each need a lot of space.

The correct response is:

Secondary and tertiary consumers have to consume a lot more food to support themselves, so there are fewer of them.

In an energy pyramid, energy is lost at each trophic level due to metabolic processes and heat. This results in less biomass and fewer individuals at the higher trophic levels (secondary and tertiary consumers) compared to producers and primary consumers, as they require more energy (food) to sustain themselves.
