Biodiversity & Resilience
Explain what biodiversity means, why high biodiversity makes ecosystems more resilient, and describe the ways human activity threatens biodiversity (habitat destruction, pollution, invasive species, climate change)
Lesson
Set out your lesson
“Biodiversity includes variation within species, between species and among ecosystems. Resilience means resisting a disturbance or recovering after it. Diversity can support resilience when organisms respond differently or provide overlapping functions. More species alone does not guarantee safety from every disturbance. Safety: No wildlife collection or release. Stop: Stop after analysing the paper networks. Do not introduce, remove or count organisms outdoors.”

Extra for the adult
Worked example. In the supplied first network, bee B still visits X after bee A is lost. This alternative link may support continued pollination. It does not prove full recovery: the card gives no pollination rate, bee B population or disease susceptibility.
Optional challenge. Give a disturbance that could affect all three pollinators and explain why diversity would not guarantee this network survives. Adult key: A disease affecting all three, or loss of both flowers, could remove the alternative links too.
What to notice. Keep the network sheet. Note if an adult named the remaining link or supplied a human benefit.

Check understanding
- Defines biodiversity at the species, genetic, and ecosystem levels
- Explains why high biodiversity makes an ecosystem more stable and resilient to disruption
- Identifies at least three human activities that reduce biodiversity
- Discusses why biodiversity loss matters for humans as well as wildlife
“If your child was asked why it matters if a rainforest is cut down even if lots of species survive elsewhere, could they explain what biodiversity means and why losing it makes whole ecosystems more fragile?”
