Which of the following is a category of invertebrate detritivores?

Invertebrate detritivores play a critical role in nutrient cycling by breaking down decomposing organic matter, which helps to recycle nutrients back into the ecosystem. Megafauna, which falls under the category chosen, includes larger invertebrates such as earthworms, woodlice, and various types of other organisms that feed on dead organic material and contribute to the process of decomposition.

Detritivores are distinct from other categories like heterotrophs, which encompass all organisms that consume organic material for energy, not limited to those that feed on detritus. They also differ from photosynthesizers, which generate their own food through photosynthesis, and predators, which actively hunt and consume other organisms. Thus, the selection of megafauna as a category of invertebrate detritivores is correct because it reflects their specific role in the ecosystem as consumers of decomposing material.
