Revision
Revision checklist
Can you explain each of these out loud, without looking? If not, re-read that lesson.
- How Photosynthesis Works: Master the word and symbol equations and how leaves are adapted for the job.
- Limiting Factors: Investigate how light, carbon dioxide and temperature limit the rate of photosynthesis.
- Aerobic and Anaerobic Respiration: Compare the equations for respiration with and without oxygen, and their uses.
- Energy in Ecosystems: Calculate the percentage efficiency of energy transfer between trophic levels.
- Read each lesson's summary and re-do its practice questions from memory.
