What term is used for organisms that break down large pieces of dead plant material into smaller pieces?

The term used for organisms that break down large pieces of dead plant material into smaller pieces is "shredders." Shredders typically include various species of invertebrates such as certain types of insects and worms that play a crucial role in the decomposition process. By breaking down larger organic matter, they increase the surface area available for microorganisms to further decompose the material, ultimately contributing to nutrient cycling within an ecosystem.

While detritivores also contribute to the decomposition process, they primarily consume smaller, already decomposed organic matter rather than breaking down larger pieces. Carnivores are animals that eat other animals, and herbivores are those that primarily consume plants. Thus, shredders specifically target larger pieces of dead plant material, making them essential for breaking down complex organic matter in ecosystems.
