A community of organisms where each member is eaten in turn by another member.

• A. Food chain
• B. Food web
• C. Carnivore
• D. Cell

Answer: (A)

Think about how energy moves through living things. The description describes a simple, linear sequence where one organism is eaten by the next, forming a direct line of who eats whom. That is a food chain. It starts with a producer that captures energy from the sun, then a primary consumer, a secondary consumer, and so on, with energy passing from one level to the next. In contrast, a food web shows many interconnected feeding relationships, not just a single line. A carnivore is an animal that eats other animals, and a cell is the basic unit of life, not about feeding relationships.
