السؤال 14

In this model, which organisms can supply dead material for the decomposers to work on?

Only the producers
Organisms at every trophic levelالإجابة الصحيحة
Only the primary consumers
Only the animals that no other animal eats

الشرح

Every organism eventually dies and leaves remains, so decomposers act on dead material coming from all trophic levels. Limiting the answer to the plants at the base fails, because dead consumers and dead predators are broken down in exactly the same way.
