In a food chain, what term is used for a feeding level?

• A. Food web
• B. Trophic level
• C. Producer level
• D. Consumer level

Answer: (B)

In ecosystems, energy moves through steps called trophic levels. A trophic level is the position in the food chain defined by who is being fed on and who is feeding on whom. Producers form the first level by capturing sunlight, followed by primary consumers that eat those producers, then secondary consumers that eat the primary ones, and so on. This term precisely describes the feeding level, whereas a food web is the broader network of many feeding relationships. The terms producer level or consumer level aren’t standard labels for the level in the chain.
