Functional Feeding Groups in Stream Macroinvertebrates

This PowerPoint accompanies Lesson 6 of the Biodiversity Teaching Experiment, focusing on the diverse feeding habits of stream macroinvertebrates. Discover how different species hunt, collect, and process prey in the stream ecosystem. Learn about predator dragonfly larvae, damselfly larvae, blackfly larvae, mayflies, crane fly larvae, caddisfly larvae, and dobsonflies. Engage students with interactive content on identifying functional feeding groups.
