- Students will be able to identify participants in the soil food web of the worm bin.
Tools & Materials
- Casting samples
The biota of the worm bin represents a very complex ecosystem. There are predators and prey. There are consumers that break down organic material and consumers that eat those consumers.
Understanding the complexity starts with careful observation but really just scratches the surface. The relationships these microorganisms have with each other is one of interdependence and maintaining the proper balance is critical to sustained health for the entire bin.
Expand the catalog of microorganisms from Lesson 3.4. Examine casting samples periodically to build out the catalog of soil food web participants. Be sure to add a section for the role that each microorganism plays. Is it as a primary, secondary, or tertiary consumer in the process? And what is their primary food supply?
