- Nutrients would not return to the soil, so plants would not grow well and plant growth would decline.
- Waste will pile up, and the food chain will break.
Why decomposers are essential :
- They clean the forest by breaking down dead things.
- They recycle nutrients back into the soil for plants to use.
