Question

Is it possible that a species may occupy more than one trophic level in the same ecosystem at the same time?

Answer 1

Yes, it is possible because the trophic level of a species represents the functional role of the organism in energy flow, which is determined by the food it takes. For example, sparrow is an omnivore. When it eats seeds, fruits or any other plant product, it occupies the primary trophic level. Whereas, when it eats worms and any other insect, it occupies the secondary trophic level.Thus, it occupies more than one trophic level in the same ecosystem.
