Answer 1

Trophic levels are formed by organisms linked in food chains.

Explanation:

Trophic levels are the positions or levels at which species feed in an ecosystem. Each step in a food chain represents a trophic level. Producers (green plants) form the first trophic level, herbivores the second, primary carnivores the third, and so on. These levels are formed by organisms linked together through food chains, with energy transferring from one trophic level to the next.
