Explain the importance of decomposers to a food web and their interaction with quaternary consumers.

Decomposers recycle the nutrients in dead organisms allowing it to completely travel through the food web cycle, from producer, to consumer and back again. Without decomposers, dead organic matter would accumulate in an ecosystem until it reached harmful levels. This recycling also applies to quaternary consumers, the predators that generally have no natural enemies, allowing the nutrients in their bodies to be recycled.
