Marine Biodiversity Observation Biotic factors: relationship/interaction that species establish with each other

A pollution-free area, the habitat of enormous variety of species

Results of measurements of some abiotic factors: Salinity = 35 g/L Carbon dioxid = 52 mg/L pH = 5,8 ( polluted areas) pH = 8,3 (non polluted areas) Temperatur = 18,5 ºC Nitrates = 10 mg/L
