The Effectiveness of CO2 Absorption Between Phytoplankton and Seagrass Beds in The West Sekotong Intertidal Zone of Lombok Island

The increasing sea surface temperature could be approved CO2 levels on the coast. It has been assumed primary productivity in intertidal zone was to absorb from water column for photosynthesis. In addition, substrate floor a potential source of decomposers. Phytoplankton and seagrasses are zone. Both them have chlorophyll, they maintain as carbon move photosynthetic systems develop metabolism body's cells. measurements were made leaves rhizomes all seagrass species. absorption process clarified by measuring growth rate, percent LOI, whole body Tetraselmis sp Dunaliella sp, which phytoplankton species isolated ecosystems. Enhalus acoroides (Ea) had highest content. On other hand, Halophila ovalis minor lowest due distribution Ea being widest, found sampling areas. factor that supported its high rate ability. coast Sekotong Barat sediment (carbon sink). presence different increase content between Tetrasemis indicates, respond differently stress ocean.
