Top-down food web stability depends on competition and predation in the higher trophic levels. Larger fish as well as octopi, squid, rays, and dolphins feast on the primary consumers. The sea urchin embryo has long been used as a model organism to address many questions in developmental biology. These are called primary consumers, or herbivores. C. Producers.
