Key Idea: Topic 2.8 explains how climate shapes biomes, how energy is redistributed by the atmosphere and oceans, and how ecosystems change across space (zonation) and time (succession). It also introduces resilience — why some ecosystems recover after disturbance and others collapse.
🌍 Biomes & climate (must-know)
Biomes are shaped by climate, not day-to-day weather.
🌬️ Atmosphere: why rainfall patterns exist (SL)
🌊 Aquatic biomes & ocean currents
Link currents to climate: they moderate coastal temperatures and influence rainfall patterns.
📍 Zonation (change across space)
⏳ Succession (change over time)
Easy compare: Zonation = space, Succession = time.
🛡️ Resilience (why ecosystems recover)
1) Weather vs climate? 2) What controls biome distribution? 3) What is zonation? 4) Primary vs secondary succession? 5) Two features that increase resilience?
