Biodiversity & Adaptation
📋 What it is
Adaptations are traits that help a species survive its habitat; more variety means a stronger ecosystem.
🗣️ Coach says
Every habitat shapes its residents. A cactus stores water for the desert; a polar bear grows thick fur for the cold. These are adaptations. And an ecosystem with lots of different species (high biodiversity) is more resilient — if one species struggles, others can fill the gap.
🧠 Memory hook
Adaptation = trait that fits the habitat. More species = a tougher, more stable web.

Hemoglo-BEATS!
😲 Whoa!
A single hectare of rainforest can hold more tree species than all of North America — biodiversity so rich scientists still find new species every year.
✅ Quick check: Why is high biodiversity good for an ecosystem?
Say your answer out loud first — then reveal.
More species means more backups — if one struggles, others can fill its role, so the whole system is more stable and resilient.
Diversity spreads out ecological roles, buffering the system against disruption.

Pick an animal and name its habitat, then one adaptation that fits it (webbed feet, thick fur, camouflage).
