Question
“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.
✓
Answer
The trophic level represents a functional level, not a species as such. A given species may occupy more than one trophic level in the same ecosystem at the same time; for example, a sparrow is a primary consumer when it eats seeds, fruits, peas, and a secondary consumer when it eats insects and worms.
