3.7.2 Populations in ecosystems PART 1

3.7.2.1 Populations and communities
3.7.2.2 Adaptations and niches
3.7.2.3 Investigating populations (data interpretation + evaluation links)

• Carefully sequenced lesson developing understanding of populations, communities, and ecosystems, with clear distinction between key terms
• Explicit focus on niche, interdependence, and competition, addressing common misconceptions (e.g. niche ≠ habitat, correlation ≠ causation)
• Active retrieval embedded throughout using MWBs, keyword recall, and structured “First, Next, Then” tasks
• Strong emphasis on interpreting ecological data, including evaluation of graphs and linking evidence to conclusions
• Students develop disciplinary thinking: evaluating conclusions, recognising limitations, and avoiding overinterpretation
• Exam practice integrated: AQA-style questions supported by mark schemes and examiner reports to model high-level responses
• Focus on precision in language (e.g. resource vs competition, population vs community) to secure marks
• Designed to support progression to A–A* through structured explanations and evaluation skills
