Answer 1

In the ocean ecosystem food web you provided, the two organisms that are omnivores are:

1. Kelp Bass - Kelp bass are known to eat both plant material (like kelp) and other fish, making them omnivores.
2. Black Rockfish - Black rockfish can also be omnivorous, eating both small fish and invertebrates along with some plant material.

The other organisms listed, such as orcas and plainfin midshipman, typically have more specific diets, while kelp and other plants are primarily producers.
