Systems Thinking in Ecology
📋 What it is
In an ecosystem everything connects — a change in one part ripples through the whole system.
🗣️ Coach says
Ecosystems are systems, meaning the parts affect each other. Change one thing — remove a predator, add pollution — and effects ripple everywhere, sometimes surprisingly. Systems thinking means asking “what else does this touch?” instead of looking at one piece alone.
🧠 Memory hook
Everything connects. Change one part → ripples through the whole system.

Why did the cactus get an award?
Because it always sticks to its principles — and to everything else!
😲 Whoa!
Removing sea otters caused sea urchins to explode, which ate the kelp forests, which wiped out dozens of other species — one change, a whole cascade.
✅ Quick check: Why can removing ONE species harm many others?
Say your answer out loud first — then reveal.
Because ecosystems are connected systems — one change ripples through the food web, affecting species far beyond the one removed.
Interconnections mean a single change cascades through the whole system.
