    Explanation:

    Correct: Cyanobacteria and diatoms are primary producers in the food chains of oceans. They are photosynthetic organisms that convert sunlight into energy and serve as the base of the marine food chain.

    Incorrect: Copepods and foraminifera are not primary producers. Copepods are tiny crustaceans that feed on phytoplankton, and foraminifera are single-celled protists that may feed on phytoplankton or other small particles.
