Which term describes a network showing the feeding relationships among organisms in an ecosystem?

• A. Energy
• B. Molecule
• C. Food web
• D. Resource population

Answer: (C)

Feeding relationships form a network that shows who consumes whom in an ecosystem. This is called a food web. It connects producers, herbivores, various predators, and decomposers into a complex map of energy flow and nutrient transfer, with arrows typically pointing from prey to predator. A food web captures many interconnected pathways, reflecting how real ecosystems work, whereas a single food chain would only show one linear path. Energy moves through this network from sunlight to producers to consumers and beyond, but the term that names the diagram of those connections is food web. The other terms don’t describe the network of feeding links: energy is about the flow of usable energy, a molecule is a chemical unit, and a resource population isn’t the feeding-network concept.
