This is especially true during the early stages of decomposition. Leaves, twigs and pieces of bark that have fallen to the ground make up leaf litter. Decomposers play a critical role in the flow of energy through an ecosystem. Plant growth would decrease over time as the nitrogen the plants took from the soil was not replaced. Here are the 9 animals that are types of decomposers. Plants contain these nutrients while growing in the ground, and then these nutrients are consumed by animals.
