Practice questions.
Use one attempt to work out what to practise next.
Try this with Marine Science
- Attempt a question independently and keep your original working.
- Mark the first point where your reasoning differs from the worked answer or criteria.
- Try a similar question and explain the step that changed.
Pick a starting point
- Where reefs grow: global and Australian distribution, latitudinal and cross-shelf patterns, and the abiotic limits on corals
- How the Great Barrier Reef formed: geological history, sea-level change since 20 000 BP, reef types and reef zonation
- Coral classification and anatomy: soft and hard corals, hermatypic and ahermatypic corals, genus keys and building the limestone skeleton
- Coral feeding, symbiosis and life cycles: nematocysts, zooxanthellae, reproduction, larval recruitment and reef accretion
- Habitat complexity and connectivity: corals as ecosystem engineers, rugosity, mangroves, seagrass, estuaries and herbivorous fish
- Reading reef health data: diversity indices, Whittaker plots, coral cover trends, water quality, tipping points and hysteresis
