Their abundance often reflects the health of aquatic environments, making them valuable bioindicators.

9. Black Fly Larvae

Black fly larvae are common detritivores in freshwater ecosystems, particularly in fast-flowing streams and rivers. They attach to rocks and other submerged surfaces, filtering organic particles from the water to feed. This behavior helps maintain water quality by reducing suspended debris and recycling nutrients back into the ecosystem. Black fly larvae serve as an important food source for fish and other aquatic predators, contributing to the aquatic food web and promoting biodiversity in freshwater habitats.

10. Freshwater Leeches (certain types)

Freshwater leeches, certain types of which are detritivores, play an essential role in freshwater biomes by consuming dead organic matter and contributing to decomposition processes. While some leeches are parasitic, others feed on decaying plant material and other detritus in ponds, lakes, and slow-moving streams. By breaking down organic matter, these leeches support nutrient cycling and provide sustenance for larger aquatic organisms. Their presence in freshwater ecosystems contributes to the overall health and balance of the environment.

11. Daphnia (Water Fleas)

Daphnia, commonly known as water fleas, are tiny crustaceans that serve as important detritivores in freshwater biomes. They filter-feed on phytoplankton, bacteria, and decaying organic matter, playing a critical role in nutrient cycling and maintaining water clarity.
