Ecological Interactions and Community Change is a Grade 12 Science 30 worksheet resource examining how ecological conditions and human activity influence populations, communities, food webs, and ecosystem services. Within an Alberta framework, students connect habitat change, invasive species, climate variability, trophic relationships, and ecological terminology to changes in Alberta ecosystems.

🌿 Explore Community Change

Students examine how habitat change, invasive species, and climate variability affect population dynamics and community structure. The resource also develops understanding of trophic relationships and energy transfer efficiency in food webs, helping students connect interactions among organisms with patterns across ecosystems.

Key ecological terms provide another layer of analysis. Students use carrying capacity, growth rate, and nutrient cycling to interpret ecosystem services and evaluate how ecological processes relate to changing environmental conditions.

🔎 Connect Ecology to Human Activity

The resource asks students to evaluate how human activities can alter ecological interactions in Alberta ecosystems. This Alberta-focused context supports discussion of community change while keeping attention on population dynamics, food-web relationships, energy transfer, and ecosystem services.

📝 Varied Student Practice

Students work through multiple-choice questions, true/false statements, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” component. These formats provide opportunities to identify ecological concepts, interpret relationships, evaluate environmental change, and communicate scientific reasoning.
