Explanation:

Mussels are consumers that eat phytoplankton, which are producers (autotrophic, plant-like organisms). Organisms that only eat producers are herbivores. Mussels do not eat other animals, so they are not carnivores or omnivores, and they are not producers themselves as they cannot make their own food.

Answer:

herbivore
