Food webs in forest ecosystems become concrete in this Grade 6 science learning stations activity built around ecosystem case studies. Students examine real forest relationships to identify producers, consumers, and decomposers or nutrient recyclers, then trace how changes can move through an interconnected food web.

Explore Food Webs Through Ecosystem Cases

Rather than treating organisms as isolated parts of a food chain, students investigate how populations and habitats are connected. The station cases focus attention on the effects of predators, insects, fire, disease, and changing food supplies. Students use those examples to reason about what can happen elsewhere in an ecosystem when one part changes.

This makes the activity useful for developing both food web vocabulary and cause-and-effect reasoning within the Alberta Trees and Forests topic.

What Students Practice

• Identifying producers within forest food webs
• Recognizing consumers and their roles in ecosystem relationships
• Identifying decomposers or nutrient recyclers
• Tracing effects of population and habitat changes through a food web
• Comparing the influence of predators, insects, fire, disease, and food availability

What You Receive

• ✅ Station cards featuring ecosystem case studies
• ✅ Student station recording sheet
• ✅ Station wrap-up activity
• ✅ Teacher guide included in the Answer Key PDF
• ✅ Learning objectives, teaching tips, discussion questions, and common mistakes in the teacher guide

Designed for Station-Based Learning

Place the case-study cards around the classroom and have students rotate between stations while recording their thinking on the station recording sheet. After the rotation, the wrap-up provides a natural transition into whole-class discussion, comparison, or review.

The structure also gives teachers specific discussion points for moving beyond simply naming trophic roles. Students can explain connections, compare ecosystem influences, and consider how a disturbance or population change may affect other organisms.

For Your Trees and Forests Unit

Use this Grade 6 food webs activity during an Alberta Trees and Forests unit, as collaborative ecosystem practice, or as a follow-up after introducing producers, consumers, decomposers, and food web relationships. The included teacher guidance supports lesson preparation and helps anticipate common student mistakes while keeping the student work centered on interpreting real ecosystem relationships.
