Marine environment: Exposed coasts, estuaries, oceans. Abiotic factors - Geological factors- oceans, ocean floor, classification of coasts. Physical factors- light, temperature, water movements (waves, tides, currents), Chemical factors-sea water, salinity, O2 & CO2 in sea water, ionic concentration & nutrients. Biotic factors –Food webs & chains, succession in marine communities, biological interactions. Zonation of marine algae: Intertidal, submerged, sublittoral zonation pattern, seasonality.
