Biodiversity & Resilience

生物多样性与生态韧性

Description

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)

Mastery Evidence
  • 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
Assessment Prompt

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?
