Question

Which of the following organisms is both a tertiary consumer and an omnivore in this food web? pufferfish damselfish tiger shark convict tang

Answer 1

In the context of a typical marine food web, the organism that is both a tertiary consumer and an omnivore among the options provided (pufferfish, damselfish, tiger shark, and convict tang) is likely the **pufferfish**.

- **Tertiary Consumer**: These are organisms that eat secondary consumers. In a marine ecosystem, this often includes larger predatory fish and some species of pufferfish that feed on other fish and invertebrates.
- **Omnivore**: Pufferfish can consume a variety of foods including algae, small fish, and invertebrates, fitting the omnivore classification.

The **tiger shark** is also a tertiary consumer but is primarily a carnivore. The **damselfish** and **convict tang** are generally considered primary consumers or herbivores, though they may eat some small invertebrates. Hence, the pufferfish fits both classifications as per the choices you've provided.
