Styrofoam plates do not decompose, This makes them unsafe for the environment. Paper or plastic plates should be used since they can be recycled.
Decomposers break down dead, dying, or decaying organic material (e.g. dead animals) into their original organic components - Carbon, phosphates, nitrates, etc. and returns them to the soil. They can then be used by producers/autotrophs for growth, and are passed on to consumers, etc.

Washing powders usually only contain one type of enzyme, though some have two or all three.
