What is the term for the sequence of organisms where each feeds on the previous?

• A. Niche
• B. Food Chain
• C. Habitat
• D. Community

Answer: (B)

The sequence of organisms where each feeds on the previous is called a food chain. It shows energy moving from one creature to the next in a straight line: a producer like a plant makes food, a herbivore eats the plant, and a predator eats the herbivore. This term specifically describes a feeding sequence, not where organisms live (habitat), the role an organism plays in an environment (niche), or the whole set of interacting populations in an area (community). In real ecosystems, energy pathways can form a more complex web, but the simple linear sequence described here is a food chain.
