primary producers
Primary Producers
  • Prokaryotes (photosynthetic & chemosynthetic)
    • Domain Bacteria
    • Domain Archaea
  • Eukaryotes (photosynthetic)
    • Kingdom Protista
      • Unicellular algae (diatoms, dinoflagellates, coccolithophorids)
      • Multicellular algae (green, brown, red)
    • Kingdom Plantae
      • Seagrasses
      • Salt marsh plants
      • Mangroves
slide3
True Plants
  • Kingdom Plantae
  • Angiosperms – flowering plants
  • Dominant on land, few in the sea
  • True leaves, stems, roots, vascular system for food/water transport

slide4
Seagrasses
  • Subtidal shelf
  • Shallow

(need light)

  • Relatively sheltered, soft-bottom areas (estuaries)
  • Mostly tropical, subtropical (eelgrass – temperate)

NOAA

slide5
Seagrasses
  • Evolved from land plants, reinvaded ocean (totally marine)
  • Roots, rhizomes stabilize sediment
slide6
Seagrasses
  • Asexual reproduction – rhizomes
  • Sexual reproduction – flowers, pollen, fruit, seeds

Salt Marsh Plants
  • Intertidal, only partly submerged
  • Relatively sheltered, soft-bottom areas

(estuaries)

  • Are land plants with salt tolerance
  • Temperate

Flax Pond →

(north of Stony Brook)

slide12
Salt Marsh Plants
  • NY distribution (yellow)
  • Also CT coast of LIS, protected bays of NJ shore
  • aka “tidal wetlands”

slide16
Salt Marsh Plants
  • Grasses stabilize mud, soil with roots, rhizomes
  • Tussocks (Spartina cordgrass with ribbed mussels)

slide17
Salt Marsh Plants
  • Protect coastline, prevent erosion
  • Filter nutrients, pollutants from runoff
  • Very productive, provide food and homes for many organisms

slide18
Mangroves
  • Intertidal, only partly submerged
  • Relatively sheltered, soft-bottom areas

(estuaries)

  • Are land plants with salt tolerance
  • Tropical
slide19
Mangroves
  • Roots (underground and aerial), pneumatophores stabilize sediment
