Question

"Is it possible for a species to occupy more than one trophic level in the same ecosystem at the same time"? Explain with the help of one example.

Answer 1

Yes, it is possible for one species to occupy more than one trophic level at the same time. The best examples are omnivores such as humans and bears.

Let us consider the case of humans. When a human eats plants he is a primary consumer but when he consumes meat, he is a secondary consumer. Thus, a human can occupy more than one trophic level at the same time in an ecosystem.
