In an aquatic ecosystem, a primary consumer is an organism that primarily feeds on primary producers, such as plants and algae. In the examples you provided:
- **Kelp bass and sea urchin**: Sea urchins are primary consumers as they feed on kelp (a primary producer).
- **The black rockfish and the kelp bass**: Both of these fish are generally considered secondary consumers; they eat smaller fish or invertebrates rather than primary producers.
- **The zooplankton and the kelp bass**: Zooplankton can be primary consumers if they consume phytoplankton (primary producers), while the kelp bass is a predator.
- **The plainfin midshipman and the kelp bass**: Both are likely to be in a higher consumer category and not directly related as primary consumers.
- **The kelp and kelp bass**: Kelp is a primary producer, and the kelp bass feeds on other organisms, so they are at different trophic levels.
From your examples, the **sea urchin** would specifically be the primary consumer, as it directly feeds on kelp, which is a primary producer. The **kelp bass**, on the other hand, is an omnivore that can eat a variety of organisms, including both primary and secondary consumers.
