"It is possible that a species may occupy more than one trophic level in the same ecosystem at the same time." Explain with the help of one example.

Explanation

Omvivores like cockroach , man , etc. feed upon member of different trophic levels so occupy different positions in different food chains e.g . When man consumes vegatables or fruits he acts as primary consumer and belongs to second trophic level , but when eats upon a herbivorous animal (e.g. goat) then he acts as primary carnivore and belongs to third trophic level.
