Another big part of plant decomposition is the breaking down of the plant by decomposers. the two main decomposers are scavengers and decomposers. Scavengers are animals that find dead animals or plants and eat them, and in the process they break them down into smaller pieces.Once a scavenger is done, the decomposers take over, and finish the job.Get price
