Common mistakes to avoid
Questions where students often pick the tempting wrong answer — make sure you know the right one:
Why does renewable energy require energy storage solutions?✗ Renewable energy can never meet demand. ✓ Solar and wind generation are intermittent - storage smooths out supply and demand.
Roughly what proportion of energy passes from one trophic level to the next?✗ 100 percent (everything transfers). ✓ About 10 percent.
What is the leading driver of global deforestation?✗ Logging for timber and paper. ✓ Agriculture (especially cattle ranching, soy, palm oil).
What are ecosystem services?✗ Government services that protect nature. ✓ Benefits people obtain from ecosystems (pollination, water purification, climate regulation, food).
