B. A balanced
Explanation:
In a balanced ecosystem decomposers breakdown dead or decaying organisms and they return nutrients to the soil to be used by plants.
A balanced ecosystem maintains an equilibrium between the biotic component and abiotic component of the system.
- The nutrient cycling between biotic component and abiotic part of the ecosystem is kept going by decomposers.
- Decomposers are organisms that breaks down dead and decaying organisms.
- They release the nutrients trapped in them in the process.
- The nutrient in the soil is in its abiotic state.
- When plants takes up the nutrient, it enters back into the biotic component.
- Decomposers helps to maintain the balance in the ecosystem.
