IGCSE Geography Antarctic Ecosystem Lesson – Food Webs, Krill & Adaptations (Full Lesson | New Syllabus 2027)

Ready-to-teach 45–60 minute lesson – no prep required
Covers food webs, adaptations and ecosystem relationships
Builds understanding of how life survives in extreme environments

Lesson Overview

A fully resourced, engaging lesson exploring how life survives in the Antarctic ecosystem, one of the harshest environments on Earth.

Students investigate Antarctic food webs, the crucial role of krill, and the adaptations that allow animals to survive extreme cold, developing a clear understanding of how biotic and abiotic factors interact.

Perfect for cold environments and ecosystem units.

What This Lesson Helps Students Do

Students will:

Describe Antarctic food webs and food chains
Explain why krill are the foundation of the ecosystem
Identify adaptations in penguins, seals and fish
Explain how abiotic and biotic factors are interconnected
What’s Included (Everything You Need to Teach the Lesson)
Fully editable PowerPoint (ready to teach)
Engaging starter: Why is krill so important?
Clear explanation: food chains vs food webs
Interactive Antarctic food web activity
Teaching slides on adaptations to extreme cold
Explanation of abiotic and biotic links
Creative plenary: “Nature’s Got Talent – Antarctic Adaptations”
