The position occupied by an organism in food chain is the

1. Analyze the question The question asks for the term that describes the position an organism occupies in a food chain, such as producer, primary consumer or secondary consumer.

2. Explain the concept A food chain shows how energy passes from one organism to another through feeding. Each feeding step is called a trophic level ("trophic" means feeding or nourishment).

• 1st trophic level: producers (green plants)
• 2nd trophic level: primary consumers (herbivores)
• 3rd trophic level: secondary consumers (carnivores)
• 4th trophic level: tertiary consumers

3. Evaluate each option

• A. Energy level: This is a general term (for example, electron energy levels in chemistry). It is not the standard ecological term for a position in a food chain.
• B. Niche: This is the role or "job" of an organism in its habitat, including what it eats, where it lives and how it interacts with others. It is broader than just feeding position.
• C. Trophic level: This is the feeding position of an organism in a food chain. ✔
• D. Biomass: This is the total mass of living organisms in an area. It has nothing to do with position.

4. Answer The correct option is **C.

5. Exam tip Link the key words: Trophic = Tier = Feeding position. Also remember that niche = role and habitat = address. WASSCE often tests these terms side by side.
