Producers in ocean biome

• Free-floating algae -- often called seaweed

• Red algae ( Rhodophyta) -- Porphyra (from which edible nori is made), dulse, Ceramium and maerl
• Green algae (Chlorophyta) --thongweed, sea lettuce (Ulva)
• Brown algae (Phaeophyta) -- like fast-growing kelp, Sargassum, Turbinaria, Dictyota, and wrack

• Phytoplankton -- tiny, one-celled photosynthetic plankton like diatoms, dinoflagellates, and coccolithophorids
• Plants

• Flowering sperms
  • Submerged: Seagrasses -- flowering plants like eelgrass and thalassia
  • Not Entirely Submerged: Mangroves -- trees that root in the shallow seafloor but grow above water
