Reading: Biodiversity and Ecosystems
Biodiversity and ecosystems is a B2 reading text in the ecological-science genre. The text covers what biodiversity is (genetic, species, ecosystem levels), why it matters (ecosystem services, food chains, climate stability, medicine, cultural value), and current threats (habitat loss, pollution, invasive species, climate change). Specific ecosystems (coral reefs, rainforests, wetlands) anchor abstract concepts. Learners read for ecological reasoning, threat identification, and conservation argument.
This worksheet builds B2 reading comprehension through an ecological-science text.

Common challenges: Ecological-systems reading at B2 is conceptually demanding — food web, trophic level, keystone species, ecosystem services, ecological balance. Cause-effect at ecological level: removing one species affects many others through complex chains. Hedged language for projections: if current trends continue, scientists estimate that, by 2050.
For: Adult and teenage learners (14+) at CEFR B2, in upper-intermediate classes, 1:1 lessons, or self-study. Maps onto Cambridge B2 First (FCE) and C1 Advanced (CAE) Reading.
