In the typical case described by this model, what does a pyramid of numbers usually show about a food web?
The number of organisms is the same at every trophic level
There are usually more top predators than producers
There are usually more organisms at lower levels than at higher ones✓Правильный ответ
Numbers of organisms cannot be compared between levels at all
Объяснение
In the typical case modelled here, each level supports fewer organisms than the level below it, so the counts fall as you move upward. The claim that numbers cannot be compared fails, because a pyramid of numbers is built precisely from those comparisons.
