JAMB 2017 Biology · Question 24
Food chain refers to the feeding relationships between animals in a ______?
Options
- A.Family
- B.phylum
- C.community
- D.group
Answer: C. community
Explanation written with AI and checked against the answer key
1. Analyze the question The question asks where a food chain operates. A food chain shows who eats whom, so we need the level of biological organization where different species live and feed on one another.
2. Explain the concept A food chain is the sequence of feeding relationships showing how energy and nutrients pass from one organism to another. It usually starts with a producer (a green plant) and moves through consumers:
Grass → Grasshopper → Frog → Snake → Hawk
Producers, herbivores, carnivores and decomposers are different species. They live together in the same habitat and interact, and that is what makes them a community.
3. Go through the options
- A. Family: This is either a taxonomic rank (organisms of closely related genera) or a group of related individuals. It doesn't include the many different species that feed on each other in a chain.
- B. Phylum: This is a broad classification category. Organisms in a phylum are grouped by body plan, not by feeding relationships.
- C. Community: This is all the populations of different species living and interacting in a particular habitat. Food chains exist here. ✔
- D. Group: This is too vague and is not a recognized ecological level.
4. Answer The correct option is **C.
5. Exam tip Remember the ecological hierarchy: Individual → Population → Community → Ecosystem → Biosphere. Anything about feeding relationships, such as food chains and food webs, points to the community. If the question adds the non-living environment, the answer becomes the ecosystem.
