Question

Scientists use different types of models to analyze the structure of ecosystems. Which characteristic is seen in a biomass pyramid, but not in a numbers pyramid?

the total number of trophic levels in an ecosystem
living matter found at each trophic level in an ecosystem
energy available at each trophic level in an ecosystem
organisms found at each trophic level in an ecosystem

Answer 1

The characteristic that is seen in a biomass pyramid, but not in a numbers pyramid, is **living matter found at each trophic level in an ecosystem**.

A biomass pyramid represents the total mass of living matter at each trophic level, while a numbers pyramid shows the number of individual organisms at each trophic level, regardless of their size or biomass.
