Trophic levels in a food web define feeding positions like producers and consumers, with insects occupying different levels as predators or prey.
Explanation:
Trophic levels in a food web represent different feeding positions such as producers, primary consumers, secondary consumers, and tertiary consumers. Insects occupy various trophic levels depending on their role in the ecosystem.
For example, insects like caterpillars may be primary consumers feeding on plants (producers) while being prey for birds (secondary consumers). In contrast, some insects like dragonflies could be secondary consumers preying on smaller insects like mosquitoes (primary consumers).
