Phytoplankton by definition are autotrophic photosynthetic protists (eukaryotic single-celled organisms), who use mineral nutrients and atmospheric CO2 , and energy from sunlight to produce organic carbon compounds, later on used as energy source in respiration. So in their ecosystem they position as primary producers.
Herbivores are organisms feeding on phytoplankton, most commonly either rotifers or crustaceans. They are called zooplankton. So herbivory in aqueous ecosystems represents the kind of predator-prey interaction, where prey is algae or bacteria, and predators are either members of zooplankton, or sometimes also Protozoa (ciliates, nanoflagellates), or alveolates (dinoflagellates). Because the latter two can also be itself autotrophic and prey for other herbivores, those relations are little bit mixed up, when it comes to phytoplankton and herbivory.
Zooplankton can be herbivores, carnivores, or omnivores. Some zooplankton species primarily feed on phytoplankton, which are microscopic plants, making them herbivores. Other zooplankton species may feed on smaller animals or detritus, classifying them as carnivores or omnivores.
Zooplankton can be herbivores, omnivores, or carnivores. Some feed on phytoplankton and other plant matter (herbivores), some feed on a mix of plant and animal matter (omnivores), and others primarily consume other zooplankton or small animals (carnivores).

omnivores ,herbivores and carnivores
Invertebrates can be herbivores, carnivores or omnivores. Caterpillars are herbivores, for example, while spiders are carnivores.
Because Omnivores are both herbivores and carnivores
Omnivores
They are omnivores
They are omnivores
