Question
Why is it not possible to have an ecosystem with only producers and no consumers or decomposers?
Show answer
Answer
Without consumers and decomposers, nutrients would not be recycled.
Explanation
- Producers make food but also die and become waste.
- Decomposers are needed to break down this dead matter.
- Without them, nutrients would not return to the soil.
- So producers could not keep growing on their own.
Every ecosystem needs producers, consumers and decomposers.
