IB Biology syllabusFirst assessment 2025

Practise using temperature and precipitation data, climographs, and biome graphs to identify ecosystems and predict where stable biomes develop.

How this is tested

  • identify biomes from climographs using annual temperature and precipitation patterns
  • state or calculate climate ranges for deserts, rainforests, tundra, or forests
  • explain how rainfall and temperature influence whether desert, grassland, or forest develops
