60-second Quick Read
- Food-web arrows point from the organism eaten to the consumer receiving matter and energy.
- Matter is recycled through organisms and the environment; energy flows through the web and is dissipated as heat.
- Common trap: one population change can cause several delayed or indirect effects, and a food web is a simplified model rather than a guaranteed forecast.
SkillrHub Practice guide
Use this short shuffled practice set to check the skill, read feedback and review missed items. Repeat quiz practice to access more of the full question bank over time.
- Worked example: Try one item slowly: underline the key words, choose an answer, then read the feedback before moving on. For Food Webs, Energy Flow and Ecosystem Change, explain the evidence or method in one complete sentence before selecting the final answer.
- Common mistake: Do not match answers by familiar wording only. Check the full AC9S7U02 idea, the units or evidence, and any exception in the stem.
- Assessment guidance: Use this short shuffled set for one attempt. Repeat quiz practice to get access to more of the full question bank over time.
- SkillrHub review path: Use feedback to name the misconception, practise a corrected example, and retest only after you can justify the answer aloud.
