Aquatic Macroinvertebrates - Ecological Role - U.S. National Park Service
Aquatic macroinvertebrates play a key role in nutrient cycling in aquatic ecosystems because they are the primary processors of organic materials. Many streams, especially those in the Southwest, are controlled primarily by allochthonous inputs of energy (Cummins 1974, Fisher 1995).
Macroinvertebrate - an overview | ScienceDirect Topics
Macroinvertebrates represent the trophic link between microorganisms/algae and fish/other vertebrates and are widely used as bioindicators due to their particular sensitivity to chemicals, large size (>50 µm) and relatively easy sampling.
