Your best bet is to do some research and find some visual aids, and make your model based off that information.
Phytoplankton make up the whole first trophic level.
Phytoplankton make their own food through photosynthesis, and are therefore autotrophs and producers.
They make it with photosynthesis, like all plants.
They are called phytoplankton. These microscopic algae are crucial to the marine food web as they serve as the primary producers, converting sunlight into energy through photosynthesis.
Phytoplankton get eaten by Zooplankton and Zooplankton get eaten by Herring but Phyotplankton make their own energy form sunlight so it's a Producer.

The scientific name of phytoplankton is phytoplankton. Phytoplankton refers to a diverse group of photosynthetic microorganisms that drift in aquatic environments.
Copepods will eat phytoplankton.
