While primary consumers are always herbivores; organisms that only feed on autotrophic plants, secondary consumers can be carnivores or omnivores. the consumers in the ocean could those bigger fishes and other organisms. For instance, urchins are a primary consumer feeding on the seaweed, kelp. Copyright © Science Struck & Buzzle.com, Inc. The primary producers of the oceans, phytoplankton, are generally consumed by microscopic organisms called zooplankton, and so the numerous animals that feed on the zooplankton are secondary consumers. The autotrophs are eaten by heterotrophs; the energy that the former possess is transferred to the latter.
