Model Answer
Food Chain: A linear sequence where each organism eats the one before it.
Example: Grass → Goat → Human
Food Web: An interconnected network of multiple food chains in an ecosystem.
Example: Grass → Insect → Frog → Snake → Eagle (linked with other chains like Grass → Rabbit → Eagle)
Source: Chapter 13, Section 13.1.1
Explanation
- Examiners expect a definition + example for each — both parts are needed for full marks (1 mark each).
- Key distinction: food chain = single straight-line sequence; food web = several interlinking food chains.
- Use examples directly from the textbook figures (forest, grassland, pond) for safety.
- Do not write long paragraphs — two crisp definitions and two examples are sufficient for 2 marks.
